What's the difference between aluminum bronze and tin bronze

1. Different elements

Aluminum bronze is a copper-based alloy with aluminum as the main alloying element. It is an aluminum bronze containing iron and manganese, belonging to high strength and heat resistant bronze.

Tin bronze A bronze having tin as the principal alloying element, sometimes with phosphorus, lead, zinc, etc.

2. Corrosion resistance and strength are different

Aluminum bronze has high strength and good wear resistance. It is used for screws, nuts, copper sleeves, sealing rings and other parts with high strength and wear resistance. The outstanding feature is its good wear resistance. Aluminum bronze can be strengthened by heat treatment, its strength is higher than tin bronze, high temperature oxidation resistance is also better.

Tin bronze corrosion-resistant, wear-resistant, has better mechanical properties and technological properties, and can be well welded and brazed, impact does not produce sparks. Tin bronze is very resistant to corrosion in atmosphere, sea water, fresh water and steam, and is widely used in steam boilers and Marine parts.

Uses of tin bronze and aluminum bronze:

Tin bronze is widely used in electrical and electronic industry, accounting for more than half of the total consumption. This is used for all kinds of cables and conductors, motors and transformers, switches and printed circuit boards. In the manufacture of machinery and transport vehicles, they are used to manufacture industrial valves and fittings, instruments, plain bearings, dies, heat exchangers and pumps.

Some domestic brands of aluminum bronze uses: QAL7 is used to make spring box corrosion resistance requirements of other elastic components, QAL9-4 is used for high strength, wear-resistant parts, such as bearings, bushing, gear, turbine, etc.; Can also manufacture nozzle, flange, flat rocker arm, bracket.
