Two Forming Methods for Hard Alloy Bar Production

Two Forming Methods for Hard Alloy Bar Production
Hard alloy rod is a round hard alloy rod, also known as tungsten steel rod. Simply put, they are tungsten steel round rods or hard alloy round rods. Hard alloy is a composite material composed of refractory metal compounds (hard phase) and bonding metals (binder phase) produced by powder metallurgy. Hard alloy, also known as tungsten steel, is relatively different in local terminology.
There are two molding methods for the production of hard alloy round rods: one is extrusion molding, which is a suitable method for producing long rods. During the extrusion process, it can be cut into any length that the user wants. However, the total length cannot exceed 350mm. Another method is compression molding, which is a suitable method for producing short bars. As the name suggests, hard alloy powder is formed by pressing with molds. The advantage of this hard alloy bar forming method is that it can be formed in one go, reducing waste. Simplify the wire cutting process and eliminate the drying cycle of extrusion method. The shortened time mentioned above can save customers 7-10 days.
Alloy materials made by combining hard compounds of refractory metals with metals through powder metallurgy. Hard alloy has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, corrosion resistance, etc., especially its high hardness and wear resistance. Even at a temperature of 500 ° C, it remains basically unchanged and still has high hardness at 1000 ° C.
