Machined Tungsten Heavy Alloy Brick For CounterweightTungsten Heavy Alloy Brick has excellent comprehensive properties
such as high density, high strength and high hardness (commonly
known as 3H alloy), and has good ductility, thermal conductivity
and thermal conductivity. It plays an important role in the
manufacture of weapons. Later, it was widely used in defense
industry, aerospace and civil industry (such as electrical
industry, drilling industry, etc.). High specific gravity tungsten
alloy has become a military and civilian alloy material. Introduction & Features of Tungsten Heavy Alloy BrickTungsten alloy cubes are mainly divided into tungsten nickel and
iron and tungsten nickel and copper, and even two series of
tungsten nickel and iron and copper. In contrast,
silicon-nickel-iron alloys have better mechanical properties and
play an important role in the defense industry and various fields
of the national economy. It is a very important new military
material in the national defense industry, and has gradually
developed into various civilian industries The high density of heavy tungsten alloy (16.5~19.00g/CC) is due to
its tungsten content between 90% and 98%. Nickel, iron, and/or
copper are used as metal bonding substrates to hold brittle
tungsten particles together, making tungsten alloys hard and easy
to work with. Nickel is the most commonly used additive in a ratio
of 7Ni:3Fe or 8Ni:2Fe (by weight).

Tungsten Heavy Alloy Brick Picture:
Application of Tungsten Heavy Alloy Brick- Die casting is a precision casting technique with less chips. It
can directly produce parts with complex shapes. Process board, high
yield, no holes, saving raw materials. In particular, the
single-phase crystallizer has poor performance. Must be able to
withstand high temperature, high pressure and metal flow erosion,
corrosion, oxidation and thermal shock. High specific gravity
tungsten alloy has good thermal conductivity and corrosion
resistance. This is a good die casting material. Compared with
copper molds, its service life can be increased by dozens of times.
