Pins For Aluminium Window Punching Tooling

Pins for Aluminium window punching Tooling is often used for punching screw holes, lock holes, install holes, weep holes, ect. We adopt SKD11, SKH51, and SKD51 materials to make sure the knives have good quality. The punching knives are much stronger than the other suppliers, we accept for custom made orders from you,...

Product Details

pins for Aluminium window punching tooling  is very hard, mainly various carbides. The main carbides are: tungsten carbide (WC), titanium carbide (TiC), tantalum carbide (TaC) and niobium carbide (NbC). In most cases, cobalt is used as a binder phase. In cemented carbide plants, cemented carbides are mixed, pressed, and sintered.

The classification of cemented carbide is performed according to ISO standards. This classification is based on the material category of the workpiece (P, M, K, N, S, H). Different carbide materials have different uses, such as turning, milling, hole machining, thread machining, grooving, and the like.
