What can we do if magnesium alloy blackened after CNC processing?
Have you ever encountered the blackening of magnesium alloy material after precision machining?
This time let's talk about a little bit about magnesium alloys and some of their properties.
As the lightest metal structural material, magnesium alloy has many advantages, such as high specific strength and
stiffness, good shock absorption, easy cutting and good shielding property of electromagnetic interference.
It is reported that the demand for magnesium alloy in the West is increasing at an annual rate of 5%. Magnesium
alloy is the third metal that human beings have begun to use on a large scale after steel and aluminum.
At present, magnesium alloys are mainly used in automobiles, aircraft, 3C (computers, cameras, digital equipment, etc.)
products.Increasingly, it has been applied to mobile phones, cars and aircraft encloses, greatly reducing the weight of
the car itself,it’s a major change in the automotive industry.
As for the automobile industry, with the proposed requirements of energy saving and environmental protection of the
society, light metal materials and environmental protection materials are more and more popular in the society.Therefore,
magnesium alloy is also becoming more and more popular in the research and development industry, becoming one of the
common materials for precision machining.
But, they also have disadvantages.
Why do they turn black after processing?
Because they are too easy to oxidize and have a low ignition point, careless control of the processing process is likely to
cause fire, which requires the manufacturer to have experienced magnesium alloy processing experience for effectively
avoiding product oxidation or processing scrap.
ZhuanXin Precision has 15 years of precision machining experience and has processed countless magnesium alloy parts. In order to avoid product oxidation, we have our own solutions and countermeasures. If you are interested, you can consult online.
