Product Description

High Strength Heavy Tungsten Alloy Drills 90WNiCu In Industrial Usage

Heavy Tungsten Alloy Drills are made of tungsten base (tungsten content is generally 80%~98%) and a small amount of nickel, iron, copper, cobalt, molybdenum, chromium and other elements. The density of high specific gravity tungsten alloy can reach 15.20 ~ 18.70g/cm3, also known as high specific gravity tungsten alloy or high density alloy material. Because tungsten alloy weighs more than twice as much as steel.

Introduction and Feature of Heavy Tungsten Alloy Drills

1. Tungsten alloy has a series of excellent properties, high specific gravity: General specific gravity 16.5-18.75g/cm3, high strength: tensile strength 700-1000mpa, strong light absorption: 30-40% higher than general lead specific gravity, high thermal conductivity: mold is 5 times that of steel; Low thermal expansion coefficient: the capacity is only 1 / 2 / 3 / 3 of that of steel, with good conductivity and resistance to welding and cutting.

2. The usual method for manufacturing heavy tungsten alloys is to mix the required tungsten, iron, nickel or copper powder, and then cold press the liquid phase to nearly full density. During the liquid phase treatment, the base tungsten alloy melts and part of tungsten enters the solution to form large tungsten particles (20 ~ 60 μ m) Microstructure of.

Application of Heavy Tungsten Alloy Drills

• Heavy tungsten alloy drill is made of high gravity tungsten alloy. The wear resistance, hardness, strength and heat resistance of the alloy are further improved, and the consistency of the products is better guaranteed. Because of these characteristics, tungsten and iridium holes have become an indispensable part of equipment in the high-tech crystal glass industry.
