Tungsten cubes can be produced not only from tungsten-copper (W-Cu) alloy powder but also from tungsten nickel iron (W-Ni-Fe) alloy powder. Although both W-Cu alloy powder and W-Ni-Fe alloy powder are types of high-density tungsten-based alloy powders, the production process parameters and physical-chemical properties of the resulting cubes differ due to the different binders. Since the basic information on W-Cu alloy cubes has already been introduced, the following presents the basic information on tungsten nickel iron alloy cubes.

Similar to tungsten-copper alloy powder and tungsten nickel iron alloy powder, tungsten-silver (W-Ag) alloy powder can also be used to manufacture tungsten cubes popular among cryptocurrency enthusiasts. In terms of physical and chemical properties, the raw materials used for tungsten cubes are all tungsten-based alloy powders, thus exhibiting characteristics of metallic tungsten, such as high density, high melting point, and good wear resistance. However, due to the different binders used in tungsten-copper, tungsten nickel iron, and tungsten-silver alloy powders, the physical and chemical properties of the prepared cubes still vary.

As one of the most common products among high-density tungsten-based alloys, tungsten alloy blocks come in shapes such as cubes, rectangular prisms, and hexagons. Although their shapes differ, their physical and chemical properties and applications are basically similar.

As a typical representative of tungsten-based alloys, tungsten nickel copper alloy is widely used in aerospace, aviation, mechanical equipment, and other fields due to its excellent thermal, mechanical, electrical, and chemical properties. The following introduces the basic information of this alloy.
