Experts believe that the company's "Technical Specifications for Automotive Mechanical Transmission Assembly" has the same technical specifications and test methods as Germany. ZF company standards, for the international general level, agreed that the company's "Automatic Mechanical Transmission Assembly" products adopt international standard product acceptance.
Precision alloy, is a kind of alloy owning special physical properties (such as magnetism, electrical, thermal and other properties).The vast majority of precision alloy is black metal based, only a few is based of nonferrous metals. It usually includes magnetic alloys, elastic alloys, expansion alloys, thermal bimetal, electrical alloy, hydrogen storage alloys, shape memory alloy, magnetostrictive alloy and etc.
In addition, in practical application some new type alloy are also considered to belonging into precision alloy, such as vibration damping alloy, stealth alloy, magnetic recording, superconducting alloys and microcrystalline amorphous alloy and etc.
