Tungsten steel

Ceramic HIP

Organization

The hard carbide phase and cobalt combine to form a two-crystal phase structure. During use, the cobalt bonding phase is eroded by cutting agents, coolants or lubricants. When the cobalt bonding phase gradually erodes, it cannot combine with the hard carbide phase, which will accelerate the wear of the carbides. The loss of cobalt is accelerated.

Single crystal phase structure. Can reduce the problem of erosion of the bonding phase, and it will not be aggravated by the increase of the number of strokes

Press life

When it is stamped to about 1.5 kks, it has been worn a lot, and it needs to be repaired by micro-processing before it can be stamped again, and as the frequency of stamping frequency increases, the amount of grinding gradually increases

The wear is still relatively small when stamping up to 8kks, the stamping quality is better, and the amount of wear changes little with the increase of the number of stamping. Long service life.

Fracture toughness

High-quality ultra-fine tungsten steel can reach 9MPa

Generally 5MPa, HIP up to 7MPa

Abrasion resistance

Ceramic is about 7 times of tungsten steel

Advantage

Friction is one-sixth of metal, which can reduce scratches on products
