Titanium Grade 7 Plate at RMB 1500/kilogram, why is Gr7 titanium alloy so expensive?
-
Gr7 titanium alloy is a corrosion-resistant titanium alloy formed by adding a small amount of precious metal Pd into pure titanium.
-
Pd is one of the ten most expensive metals in the world, with a reference price of 71406.81/kg. Palladium is the second most expensive metal in the commodity market.
-
It is about 30 times rarer than gold or platinum. Between 2001 and 2018, the value of palladium was lower than that of gold and platinum. From February 2019, the price of palladium began to exceed that of gold. The main reason is that it is often used as a catalytic converter in diesel vehicles, and the global regulation of fuel vehicles has been tightened. At the same time, there has been a European diesel emission scandal, which has led to a rapid increase in the market demand for palladium by automobile manufacturers. As a result, the value of palladium has significantly exceeded that of gold.
-
Palladium is an indispensable key material in high-tech fields such as aerospace, aviation, navigation, weapons, and nuclear energy, as well as in the automobile manufacturing industry. For example, the most common use of palladium is a catalytic converter, which can convert up to 90% of all harmful gases in automobile exhaust gas into substances with less toxicity, especially the investment variety that cannot be ignored in the international precious metal investment market.
Application of Gr7 titanium alloy
manufacturing press parts
Such as forged titanium fans, press plates, blades, cast titanium press casing, intermediate casing, bearing housing, etc.
spacecraft
It mainly uses the strength, corrosion resistance, and low-temperature resistance of titanium alloy to manufacture various pressure vessels, fuel tanks, fasteners, instrument straps, frames, and arrow shells.
Aerospace
Titanium alloy plate weldments are also used in the construction of earth satellites, spacecraft and space shuttles.
Industrial and shipbuilding
It is mainly used in dilute hydrochloric acid, dilutes sulfuric acid, dilutes phosphoric acid environment, and is also widely used in titanium equipment to prevent crevice corrosion, such as tubular heat exchangers, agitators, textile spinneret, and other components.
