Since tungsten metal is hard to be machined, the common remotion process could not make it perfect. But Metal Injection Molding (MIM) is an ideal manufacture process to making tungsten alloy cubes. MIM is suitable to manufacture the metal and ceramic component with the property of complex three-dimensional structure, high density, high rigidity, high precision, etc. The smaller, more precise, more complex, MIM have more advantage, the density comes 95%-98%. The high density of WHAs makes it possible to significantly reduce the physical size of components. This in turn, gives the benefit of greater control of weight distribution and increases the sensitivity of controlling mechanisms. Where a large mass must be housed within a restricted area, tunsten alloys are the ideal material.
Mix tungsten powder and binder→Injectiong mould the part→Debind the part →Sinter the part.
Density - Typically 95-98% of wrought material. Mechanical Properties - Comparable to wrought alloys of similar composition. Complexity - Geometries comparable to plastic injection molding. Surface Finish - As processed, 32 rms or better. Corrosion Resistance - Comparable to wrought alloys of similar composition. Alloy Selection - Many ferrous, nickel-based and copper-based alloys available.
