Advantages and disadvantages of die-casting aluminum alloy applications

by xiaolong luo cnc machining shop
First, the advantages:

1. The thermal conductivity, electrical conductivity and cutting performance of aluminum alloy are good;

2. The aluminum alloy wire shrinks less, so it has good filling performance;

3. The aluminum alloy has small density and high strength, and its ratio of tensile strength to density is 9-15. When working at high temperature or low temperature, it also maintains good mechanical properties;

4. Aluminum alloy die casting has good corrosion resistance and oxidation resistance. Most aluminum alloys have good corrosion resistance in fresh water, sea water, concentrated nitric acid, nitric acid, gasoline and various organic substances.

Second, the shortcomings:

1. Low hardness, and at the same time, wear resistance is also poor;

2, the volume shrinkage during solidification is relatively large, about 6.6%;

3. The die casting parts coefficient of linear expansion is relatively high;

4, easy to stick mold, need to strictly control the iron content in the range of 0.8% -0.9%;

5. The melting point is low and the use of high temperature is limited.

Third, the application:

Aluminum alloy can replace bronze as low- and medium-speed medium-temperature heavy-duty bearings, and the price is 50% lower than that of bronze bearings.

Profiles can also be produced by continuous casting or centrifugal casting for the manufacture of bushings, bushings and the like.

It can also be used to make molds, which are widely used in the production of bearings, various pipe joints, pulleys and various types of impact and wear castings.

Die-casting aluminum alloy has a wide range of applications, mainly used in automotive, engineering construction, power, electronics, computers, household appliances, high-fidelity speakers, military ships, aviation, aerospace and other military fields
