Main alloy designations: ZTC4.ZTA15,ZTA7,ZTA10,3B,pure titanium and so on.

Compared to carbon steel and stainless steel,titanium alloy castings are lighter and

have higher specific strength. It also has much better corrosion resistance against

sea water and acid. When exposured in sea water for continuous 18 years, only to

find its surface color changed.

Titanium casting is used for harsh environments where corrosion resistance is critical. These

castings are typically specified for environments such as wet chlorine gas, hydrochloric acid,

sulfuric acid, nitric acid, acetic acid, and saltwater. We are able to take your custom needs

as well as low-volume projects and produce them.
Casting Methods:
Machined graphite mold casting
Ceramic mold investment casting
