Tungsten Alloy Wear-resistant Blank Shaft Sleeve PM Sintered Parts

Product Introduction

Tungsten alloy is an alloy based on tungsten (about 90-98%) and is added with nickel, iron, copper, or other components. The specific gravity is generally 17.0-18.5. This alloy has good plasticity and machinability, good thermal conductivity and electrical conductivity, and excellent absorption capacity for gamma rays or X-rays. This alloy is mainly used in the manufacture of gyroscope rotors, guides, and shock absorbers for aviation and spacecraft; die-casting molds, tool holders, boring bars, and automatic watch weights for machinery manufacturing; armor-piercing projectile cores for conventional weapons, Rivet heads and switch contacts for electrical products; in addition, it is also used to manufacture various radiation-proof shielding components, etc.

In the field of aerospace, tungsten alloys are widely used, and with the development of the aviation industry in the future, it will usher in a new wave of growth. A large number of carbide tools (CNC machine tools, etc.) are used to cut the fuselage, and some tungsten alloys are used in the manufacture of components, such as aircraft engine materials and thermal insulation coatings.

1. Tungsten alloy is an indispensable material in the manufacture of aircraft engines. The temperature of an aircraft engine is as high as more than 2000 degrees, and only titanium-tungsten-molybdenum alloy can withstand such a high temperature. Aircraft engines need to be insulated with other materials, and our country has used composite materials for heat insulation: a layer of seed powder, and a layer of titanium-tungsten alloy plate pressed into shape. Because the coating of tungsten material is equivalent to putting a layer of protective cover on the engine parts, it will not take up the weight, but also improve the performance and lifespan, which is the best of both worlds. In addition, in the important repair and maintenance of the engine, surfacing welding and spraying tungsten coating is also necessary maintenance work for the aero-engine, which is very important to prolong the service life of the engine.

2. Tungsten alloy is currently the most effective material for balancing the overall weight of the aircraft. The balance parts generally use tungsten-based high-density alloys. Tungsten-based high specific gravity alloys are usually divided into temporary and permanent in aircraft. In addition, in helicopter production, tungsten alloy counterweights are also incorporated into the high control system of many propeller designs to prevent overspeeding. Tungsten alloys can be made into blades to compensate for the balance built into a single blade in a helicopter.

3. Tungsten alloy is used in the manufacture of the outer edge rotor of the aircraft navigation gyroscope, and the navigation gyroscope is a very important component in the fields of satellites, missiles, rockets, and aerospace.

4. The brake pads of the aircraft are made of tungsten alloy (tungsten-molybdenum alloy and tungsten-manganese alloy). The temperature generated by the aircraft during the braking process has already melted and deformed other metals. The performance and characteristics of tungsten alloy's high-temperature resistance are ideal materials.

5. Tungsten alloy is an ideal shock-absorbing material. Tungsten alloy weights can be used to adjust the oscillation frequency of the triangle and laser beam, and the curved rod made of tungsten alloy is ideal for vibration damping in high density.
