Non-magnetic hard alloy plate PM sintered parts are made of non-magnetic materials with excellent non-magnetic properties, used for magnetic field press forming molds and corrosion-resistant tools. It has high hardness and high wear resistance, good bending strength, impact toughness, chemical inertness, strong processability (cutting, forging and heat treatment, etc.), and is not easy to deform. It is mainly powder molding and sintering. According to the classification of pressing, it can be divided into two types: ordinary pressing and isostatic pressing. Ordinary pressing is upper/lower mold pairing, two-way pressing, isostatic pressing products are six-sided simultaneous pressing, hard alloy plate products pressed by isostatic pressing, with uniform density and pressure, which can reduce pores and blisters. According to sintering, it can be divided into ordinary sintering and overpressure sintering. Overpressure sintering is mostly thick plates, which can reduce the internal stress of cemented carbide.
Non-magnetic cemented carbide refers to hard alloy materials with no magnetic or weak magnetic properties. It continues to the final product, only depending on the amount and form of residual chlorine, and has a degree of difference. Using non-magnetic cemented carbide, the structure and phase composition of tungsten steel will change with different cooling conditions. Using this feature to heat treat tungsten steel can improve its physical and mechanical properties, and replace non-magnetic steel with its excellent performance. It can double the work efficiency.
Carbide sheet
A tungsten carbide plate is also called a tungsten steel plate, which is a square tungsten steel material. Some are square and some are rectangular. In the mold factory, make mold cores, inserts, special-shaped punches, wear-resistant parts, etc.
Tungsten carbide plate/tungsten steel plate can be divided into thick plate and thin plate. Ultra-thick and ultra-thin are more difficult to process. Ultra-thin products are easy to deform during sintering. If the tungsten steel plate is not sintered well, it will be like an arch bridge. However, if the board is too pure when the binder is volatilized, it is more difficult to volatilize, so it is easy to form some small sand holes.

In order to avoid sand holes in the tungsten steel sheet, you can choose isostatic pressing and overpressure sintering, which can improve the quality of the tungsten steel sheet and avoid cracking of the tungsten steel sheet during wire cutting.
There are many kinds of materials for tungsten carbide plates/tungsten steel plates. You can choose different materials according to your different needs. The general direction can be followed. The hardness of tungsten steel for wear-resistant parts is high, and the toughness and strength of impact-resistant products are high. material.
