Ti-0.2Pd (Grade 7) Introduction

Ti-0.2Pd (Grade 7) Titanium alloy is α type titanium alloy which made by add small quantity precious metal palladium into pure industrial titanium. The addition of palladium has not only significantly improved the corrosion resistance of alloy in reducing medium, but also improved its corrosion resistance in oxidizing medium. In high temperature, high concentration of various chloride media, Ti-0.2Pd alloy has the strongest anti-crevice corrosion resistance. Ti-0.2Pd also has various properties similar to that of industrial pure titanium, so the alloy is widely used in chemical industry, especially petrochemical industry. The main products of Ti-0.2Pd alloy are titanium sheet, titanium rod, titanium tube, casting and titanium wire.

Ti-0.2Pd (Grade 7) Application

Ti-0.2Pd alloys are mainly used in dilute hydrochloric acid, dilute sulfuric acid, dilute phosphoric acid environment and widely used in titanium equipment to prevent crevice corrosion. Such as a tubular heat exchanger made from Ti-0.2Pd alloy for dilute hydrochloric acid, dilute sulfuric acid and dilute phosphoric acid. In the textile industry, it is used as a spinneret, a large number of titanium equipment flange rings and diamond gaskets are made in acetaldehyde devices. Other devices also use Ti-0.2Pd to make flanges and joints. In addition, the alloy is also used as a structural material for C2H2Cl2.
