Titanium Alloy Spring Mattress: From Super Battleship To Comfortable Sleep

Titanium Alloy Spring Mattress: From "Super Battleship" to Comfortable Sleep

In recent years, high-end mattresses made of titanium alloy springs have become popular among high-end consumer groups in some first-tier cities.

"Titanium alloy" is a rather uncommon word for most consumers, but for senior military enthusiasts, it is a word that is exciting and sensitive enough to make them feel. Because too many legends and stories in the history of science and technology originate from "titanium alloy", the most famous is undoubtedly the story of "goldfish".

During the Cold War, the former Soviet Union developed a "super" nuclear submarine to fight against the US aircraft carrier. Due to the submarine code name "Alfa", it is also known as the A-class nuclear submarine. The distinguishing feature of the A-class nuclear submarine is that the shell is made of all-titanium alloy. Due to the limitations of the smelting process and other factors at that time, the manufacturing cost of titanium alloy shells was extremely expensive, even higher than the same weight of gold, so it was called "fish made of gold".

With such a high cost, even the rich and wealthy Soviet Union in the Brezhnev era had to change back to the steel hull after building a few ships. However, although titanium alloy material is extremely expensive, it is worth the money. The fastest speed of the "Goldfish" A-class nuclear submarine exceeds 45 knots/hour (about 90 km/hour), which is faster than the speed of most torpedoes, so it is almost impossible for the "Goldfish" to be sailed at full speed. hit. And the Guinness World Record for the fastest underwater dive is still unbroken 40 years later.

The curtain of the legend of titanium alloy is thus pulled. Its three unique advantages are unmatched by other steel materials. They are (1) high strength, no deformation; (2) corrosion resistance, durable; (3) Weight quality, easy maintenance. The same is true for mattresses made of titanium springs.

Counting the "Super Properties" of the "Super Material"

(1) High strength, no deformation

In addition to the A-class nuclear submarines made of titanium alloy materials in the former Soviet Union, there are also the test boats "Komsomolets". Benefiting from the advantages of titanium alloys, this submarine has set a diving record for military boats with a depth of 1200 meters, while the diving depth of steel hull submarines in the world is generally only about 300 meters.

As we all know, the deeper the submarine dives, the higher the strength of the hull material is required, otherwise, the submarine will have the risk of water leakage or even sinking due to the deformation of the hull. According to the data, the yield resistance of pure titanium is as high as 180KG/mm2, so the strength of the titanium alloy made from it is generally several times higher than that of high-strength steel.

Mattresses are durable consumer goods, and consumers will use them continuously for several years or even more than 10 years after purchase. Every time consumers turn over and get up during sleep, it is a test of the spring and consumption of service life. If a single mattress is used for 10 years, the physical deformation of a single spring will exceed 100,000 times. The high-strength titanium alloy spring has excellent physical properties of resistance to yield, so it can still maintain its original state after many years of use.

(2) Corrosion resistant and durable

The reason why titanium alloys can be favored by submarine designers is that in addition to strong pressure resistance, it is more resistant to corrosion. Seawater itself is a strong corrosive medium, and the microorganisms and attached organisms in it will accelerate the corrosion process of metals. However, the corrosion resistance of titanium alloy is much better than that of stainless steel, which can increase the service life of the hull.

In addition, titanium alloys are also widely used in stomatology instruments, such as the inner support frame of porcelain teeth, many of which are made of titanium alloys. This is because titanium alloys are highly resistant to corrosive liquids such as saliva and can be used for decades.

The metal springs used in inferior mattresses will rust as the use time increases, and the degree of rust is affected by the quality of the spring materials and the local climate. Generally speaking, the higher the rust degree of the spring and the heavier the aging degree, the more serious the function attenuation of the original spring will be. Therefore, mattresses made of corrosion-resistant titanium alloy springs are very beneficial to maintain the functionality of the mattress for a long time.

(3) Lightweight and easy maintenance

In addition to submarines, the most used titanium alloys in military equipment are aircraft. Generally speaking, the higher the proportion of composite materials such as titanium alloys, the better the maneuverability of the fighter. For example, the Russian Su-27 series titanium alloy consumption is roughly 23%, and the US F-22A is roughly 36%. This is because, in addition to their high strength, titanium alloys are also light in weight. Under the premise of a certain engine thrust, the larger the proportion of titanium alloy used in the fighter, the higher the thrust-to-weight ratio, the greater the range of motion, and the greater the advantage in the process of aerial combat.

In addition, Americans once used titanium alloys smuggled from the former Soviet Union to build a famous reconnaissance aircraft-"Blackbird" SR-71. This titanium consumption accounts for 93%, and the aircraft called "all-titanium" is the only manned aircraft in the world that has reached the "Double 3" indicator, that is, the flight speed is 3 times the speed of sound and the ceiling is 30,000 meters.

In view of this characteristic, the titanium alloy spring mattress is about twice lighter than the steel wire spring, which is not only convenient for transportation but also extremely convenient for maintenance. Many mattresses are explained in the maintenance manual. In order to avoid the unilateral spring stretching and deforming due to the consumer's sleeping direction preference, the mattress needs to be turned over every month or so. face mattress. Ordinary mattresses need more than two people to turn over, while titanium alloy spring mattresses can be easily turned over by only one adult.

Which is better and which is worse?: Titanium alloy spring PK steel wire spring

In theory, mattresses made of titanium alloy springs are superior to ordinary spring mattresses on the market in terms of comfort, ease of maintenance, and durability. If so.

For ordinary mattresses on the market, most of the support systems use steel wire springs. However, due to different materials, the steel wire springs will ultimately vary greatly. The quality of the steel wires determines the strength and resilience of the springs. Therefore, consumers are advised to choose the best technology. , Reputable big brand mattress.

Some big brand mattresses use steel wire springs that are made of several high-quality steel wires and have strong resilience. For example, the Simmons brand independently bagged mattresses made in the United States, some products use steel wire springs. It is made of several strands of thin steel wire.

In addition, some domestic brands of steel wire mattresses are also excellent in workmanship. For example, brand mattresses such as Xilinmen and Emma, almost all use chrome plating and other metal processes for the steel wire layer. In this way, the oxidation and corrosion of the steel wire and the permanent deformation are avoided.

In titanium alloy springs, the amount of titanium content is very important. It is also recommended that consumers buy products made by regular manufacturers and big brands. Among the big brand titanium alloy spring mattresses, there is no doubt that the titanium alloy spring mattresses made by the American brand Sealy are the most famous.

The SRX titanium alloy spring used by Sealy, combined with the ApexTM Encased Coil beautiful posture independent barrel design, not only has the characteristics of lightweight, non-magnetic, long service life, etc., but also can automatically sense the body curve, protect the spine, and reduce turn over. frequency, and promote blood circulation.

It is understood that Sealy's titanium alloy mattresses sold in China are divided into two types: domestically assembled and pure American-made. It is reported that their commonality is that key materials such as titanium alloy springs are imported from the United States.

If Sealy's original imported products from the United States are sold through direct sales, more consumers will be able to afford these imported mattresses at high prices. It should be said that the popularity of titanium alloy spring mattresses in the domestic market will be an important factor. Great benefit.
