Battery stretching applications

Tensile Series Cemented Carbide is a type of Cemented Carbide material specially designed for use in the machining areas of metal drawing, forming and stamping.

These materials usually have the following characteristics:

High hardness and wear resistance: the hardness of tensile series Cemented Carbides is very high, usually in the range of 88.5-94.5 HRA, which allows them to withstand the high stresses and abrasions generated during metal drawing.

Good adhesion resistance: During the stretching process, the metal may adhere to the mould, so Tensile Cemented Carbides usually have excellent adhesion resistance, reducing the adhesion of the metal to the surface of the mould and improving the quality of the stretched part.

High strength and toughness: Tensile series Cemented Carbide not only has high hardness, but also has a certain degree of strength and toughness, which can withstand shocks and vibrations during the stretching process, and reduce the fracture and breakage of the mould.

Excellent thermal stability: During the stretching process, the mould will generate heat due to friction, so tensile series Cemented Carbide needs to have excellent thermal stability to maintain the stability of the mould size and shape, and avoid dimensional changes caused by thermal expansion.

Good machinability: In order to create complex shapes for stretching moulds, tensile series Cemented Carbide should have good machinability, such as easy grinding and EDM (electric discharge machining).

        The products are involved in areas such as the moulding of round and square shells for new energy vehicle batteries, the moulding of cosmetic shells, the extrusion and stretching of thermos cups with mirror spinning down to 0.07mm, the moulding of hexagonal bars and seamless steel pipe profiles, and so on.
