Alloy Die Casting
Alloy Die Casting Company provides die castings made of aluminum and zinc/aluminum alloys. Five-Star Tooling offers precision engineered.
Die casting molds are usually constructed from hardened steel and they are often the most expensive component in a die casting machine.
These molds can handle a range of different alloy families like zinc, magnesium, copper, tin, bronze, brass, lead and also aluminum.
However, die-casting is generally most effective on metals with low fusing temperatures. For this reason, the common die casting alloys fall into a handful of categories based on their composition and material properties.
Die-cast aluminum alloys are often used in automobile parts and gears. They are generally stronger and lighter than most zinc-based materials, but tend to be more expensive to create.
Using aluminum alloys can reduce the need for finishing treatments, such as plating. Magnesium may be added to this alloy to improve its tensile strength while nickel can be included to increase rigidity and provide a higher surface finish.
1. Aluminum alloy has good thermal conductivity, electrical conductivity and cutting performance.
2. Aluminum alloy has good filling property because of its small linear shrinkage.
3. Aluminum alloy has low density and high strength. Its ratio of tensile strength to density is 9-15. It also keeps good mechanical properties at high or low temperature.
4. Aluminum alloys have good corrosion resistance and oxidation resistance. Most of them have good corrosion resistance in freshwater, seawater, concentrated nitric acid, nitric acid, gasoline, and various organic compounds.
1. Low hardness and poor wear resistance at the same time.
2. During solidification, the volume shrinkage is larger, about 6.6%.
3. The coefficient of linear expansion is relatively high.
4. Easy to stick die, iron content should be strictly controlled in the range of 0.8% to 0.9%.
5. Low melting point limits the use of high temperature.
Aluminum alloy can replace bronze as a low, medium speed, medium-temperature, and heavy load-bearing. The price is 50% lower than that of the bronze bearing.
Profiles can also be produced by continuous casting or centrifugal casting to produce bearing bushes, bushings, etc.
It can also be used to make moulds. It is widely used to make bearings, pipe fittings, pulleys and castings which are impacted and worn.
Die-casting aluminum alloy is widely used in automobile, engineering construction, power, electronics, computers, household appliances, high-fidelity speakers, warships, aviation, aerospace, and other military industries.
Zinc Alloys Die-casting
1. Cast zinc alloy has good fluidity.
2. Cast zinc alloy has good corrosion resistance
1. The most common defect of zinc alloy die casting is surface blistering.
1. It is suitable for die casting instruments, automotive parts shell, etc.
