Hongkong DDQ Applied Materials Co.,Limited is one of the leading suppliers for the machined and precision engineering products of Titanium and its Alloys, Nickel and its Alloys, and some other advanced metal products in China. 
 
We mainly focus on these corrosion-resistant alloys .For example
 Titanium(wholeseries),Molybdenum(screws),Tantalum,Waspaloy ,Hastelloy(X,B,C4,C22,C276),Monel(400,500,404),Inconel(600,602CA,625,718,725),Nimonic(263,75,80A,90),Incoloy(028,800,800H,800HT),Invar(36),etc.

Tantalum is a greyish silver, heavy, and very hard metal. When pure, it is ductile and can be drawn into fine wire, which can be used as a filament for evaporating metals such as aluminium. Tantalum is almost completely immune to chemical attack at temperatures below 150°C, and is attacked only by hydrofluoric acid, acidic solutions containing the fluoride ion, and free sulphur trioxide. The element has a melting point exceeded only by tungsten and rhenium.

Molybdenum is a silvery-white, hard, transition metal. Scheele discovered it in 1778. It was often confused with graphite and lead ore. Molybdenum is used in alloys, electrodes and catalysts. The World War 2 German artillery piece called "Big Bertha" contains molybdenum as an essential component of its steel.
