Ordinary aluminum bronze

 

Introduction to the

Aluminum content is generally not more than 11.5%, and sometimes to join the right amount of elements such as iron, nickel, manganese,

Aluminum bronze

To further improve performance. Aluminum bronze is heat treatment strengthening, its strength is higher than tin bronze, resistance to high temperature oxidation is better also.

Have high strength, good abrasion resistance for high strength screw, nuts, copper sets, sealing ring, etc., and wear resistant parts, the most prominent feature is its good wear resistance.

To contain iron, manganese, aluminium bronze has high strength and abrasion resistance, can improve the hardness after quenching, tempering, has good high temperature corrosion resistance and oxidation resistance in the atmosphere, fresh water and seawater corrosion resistance is very good, can be well machinability, welding is not easy to fine welding, hot processing good under pressure.

At present, China's energy production.

Commonly used domestic brands

QAL7

Plate, belt, line

With high strength and elasticity, in the atmosphere, fresh water, sea water, and some of high corrosion resistance in acid, can be hot and cold pressure processing, electric welding and gas welding and brazing.

Spring box of other elastic element require corrosion resistance

QAL9-4

Plates, tubes, rods

With high intensity, good friction resistance and good corrosion resistance, hot working, can be welded, but not easy brazing.

High strength, wear-resistant parts, such as bearings, sleeves, gears, turbine, etc.; Can also be made to take over the mouth, flange, oblate rocker arm, support, etc

QAL10-4-4

Plates, tubes, rods

Under 400 ℃ has the stable mechanical properties, good anti-friction property, in the atmosphere, fresh water, sea water corrosion resistance is very good, but hot working, can be welded, but not easy brazing.

High strength wear resistant parts box under 400 ℃ working parts, such as bearings, sleeves, gears, ball seat, nut, flange, etc

Special aluminum bronze

 

 

Aluminum bronze

Here mainly refers to the aluminum content in more than 11.5%, less than 15% of aluminum bronze. In addition to the aluminum element composition and ordinary aluminum bronze.

Because of the aluminum content difference, make special aluminum bronze than the strength of the alloy steel is more high and close to the hardness of alloy steel. Is widely used for force structure, transmission parts and so on.

In addition, due to its good corrosion resistance, resistance to pressure and anti-wear ability, also used for high-speed train gear drive shaft.
