Product Description

Magnesium alloys have advantages in heat dissipation relative to alloys. For heat sinks of magnesium alloy and aluminum alloy materials of the same volume and shape, the heat (temperature) produced by a certain heat source is easier to transfer from the root of the heat sink to the top of the magnesium alloy than the aluminum alloy. Speed, the top is easier to reach high temperature. That is, the temperature difference between the root and top of the radiator made of aluminum alloy material is smaller than that of the radiator made of magnesium alloy material. This means that the temperature difference between the air temperature at the root of the heat sink made of magnesium alloy and the air temperature at the top is larger than that of the heat sink made of aluminum alloy material, so it accelerates the diffusion and convection of the air inside the radiator and improves the heat dissipation efficiency. Therefore, at the same temperature, the heat dissipation time of magnesium alloy is not half that of aluminum alloy.
Because magnesium alloy has good thermal conductivity and low cutting force, the heat dissipation rate during processing is very fast, so the tool life is long and the amount of sticking is small, which can reduce tool costs and shorten the downtime required for tool replacement. Because magnesium is easy to cut, its chip breaking performance is very good, under normal circumstances, only one finishing process can achieve the required final surface finish.
Weight: magnesium alloy is 36% lighter than aluminum alloy, 73% lighter than zinc, and 77% lighter than steel.
Specific strength: magnesium alloy is equivalent to aluminum alloy and steel, much higher than fiber reinforced plastics.
Wear resistance: the wear resistance of magnesium alloy is much higher than that of die-cast aluminum alloy A380.
Damping performance: magnesium alloy is 30 times higher than aluminum alloy.

Company Profile

Sino Zheng Industrial Inc. is one of a leading & professional suppliers of forging magnesium wheel, magnesium welding wire, magnesium rod as well as magnesium alloy profiles in Zhengzhou China. Our company uses advanced production technology and automation equipment to ensure the high quality and high stability of magnesium alloys. Our magnesium alloy rods are refined by a special process, with small grains, uniform inside and outside, low impurity content, and no peeling; the company's die-casting production line uses these magnesium alloy rods as raw materials to produce magnesium alloy bicycle frames, rims, and magnesium alloys. High-quality products such as crossbow racks.

Our company has now developed a formula and process for producing high-quality magnesium alloys, which are inimitable. Magnesium alloy welding wire produced with this formula and process can realize compatible welding between different magnesium alloy materials, that is, different materials of magnesium alloy can be welded with one kind of welding wire, and have the advantages of small thermal effect zone, deep welding penetration, and no blistering. In particular, the 1.2mm magnesium alloy welding wire produced uses a one-time extrusion process to replace the original extrusion and then drawing process. Relying on the excellent technical team in the industry, the company continuously expands the application range of magnesium alloy materials through technological innovation, product innovation and process innovation, and contributes to the development of my country's magnesium alloy industry.

Our company is currently a professional manufacturer of magnesium alloy welding wire in China. The magnesium alloy welding wire produced by the company has specifications such as 1.2mm, 2.4mm, 3.2mm, etc., all of which are produced by one-time extrusion molding process with stable quality. With these magnesium alloy welding wires, different types of magnesium alloys can be welded together. The heat effect zone of the welded parts is small and the weld strength is higher than the non-welded zone. The bicycle frames welded with these magnesium alloy welding wires can achieve more than 150,000 vibration tests without cracks.

The application of magnesium alloy welding wire completely solves welding problem of magnesium alloys, can promote the wide application of magnesium alloys in military, aerospace, and civil applications, can increase the total application of magnesium alloys in the country, and maximize the high reserves of magnesium alloys in the country propelling the magnesium industry into a stage of rapid development will bring a material revolution to our country.
