International Standard Magnesium Alloy Welding Wire For Electronic Products
Introduction:
Magnesium alloy is a good light structural material, which is widely used in spatial technology, aviation, and auto
Industrial departments such as cars and instruments. Compared with plastic, magnesium alloys have light weight, high strength, good vibration reduction, good thermal fatigue performance, difficulty in aging, and good thermal conductivity, strong electromagnetic shielding ability, and very good die -casting process performance, especially easy to recycle The advantages are a new generation of high -performance structural materials replacing steel, aluminum alloy and engineering plastics. In order to adapt to the development trend of highly integrated and light and small, electronics and communication devices, magnesium alloys are the ideal of transportation, electronic information, communication, computer, sound -like equipment, laptop tools, motors, forestry, textiles, nuclear power devices and other product shells. Material. Developed countries attach great importance to the development and application of magnesium alloy, especially in the application of portable electronic products such as automotive components and laptops. It grows at a rate of 20%each year. It is very eye -catching and the development trend is amazing.

Use
Magnesium alloys and casting magnesium alloys are widely used in the welding of optical instruments, automotive accessories and civilian magnesium products and crafts. It is a special magnesium compound welding wire for welding and repairing magnesium alloy fracture, cracks, and needle -eye air pores.
Magnesium alloy has a good earthquake resistance and can withstand a greater impact load than aluminum, so there are many forging and casting products abroad.
Advantage:
1. Scaled stability: This is one of the characteristics of magnesium. When it takes out from the mold, the product only needs to cast stress for the residual casting, so it does not need to anneal and dehuminate the need. In the case of loading, this metal can also appear well resistant to creep characteristics. For example, AM die castings accept 100 hours under the condition that 0.1%to 0.5%are only 0.1%to 0.5%.
2. Outstanding cutting performance: Magnesium has better processing and cutting characteristics than aluminum and zinc, which promotes magnesium to become the most easy -to -cut metal data.
3. High shock absorption performance: Magnesium has excellent stagnation shock absorption performance, which can absorb vibration and noise. This is very important to use as a device shell to reduce noise transmission, and supply anti -impact and anti -outer damage damage.
