What Are the Advantages of Zamak 5 Alloy?
Due to the Zinc 5 properties, it has a lot of advantages to offer, for example:
- This alloy has a great strength-to-weight ratio. That means it is suitable for making casting components that need to be lightweight but should be able to withstand great impact.
- Zinc 5 casting parts show lesser defects than most other metal or metal alloy casting parts. For this reason, the cost of post-processing reduces a lot.
- Using this alloy will help to avoid many problems caused by other metal alloys. For example, magnesium alloy has fire hazard problems, aluminum alloy has leakage problems, etc. which are avoidable by using the Zinc 5 alloy
- This alloy has a very good plastic deformation property which allows easy machining, shaping, forming, of casting parts.
- The Zinc 5 alloy has higher strength, hardness, and resistivity to corrosion than most other alloy metal which is very useful for making certain casting parts.
What Are the Applications of Zamak 5 Alloy?
The Zamak 5 alloy is used in many industries such as:
- In the automobile industry, this alloy helps to make many parts such as clutch, metal shaft, gear changer, etc.
