High Toughness Magnesium Alloys Tubes For Aircrafts With Low Density

Introduction:

A magnesium alloy formed by adding alloying elements to magnesium base suitable for the production of parts by casting method. According to alloying elements, it can be divided into: magnesium aluminum zinc cast magnesium alloy, magnesium zinc zirconium cast magnesium alloy, magnesium rare earth zirconium cast magnesium alloy. The cast magnesium alloy brand is composed of pinyin letters ZM and numbers.

Feature:

1. Magnesium alloy has low heat capacity, fast solidification speed and good die casting performance. Magnesium alloy is a good die casting material, it has good fluidity and rapid solidification rate, can produce fine surface, clear corners parts, and can prevent excessive shrinkage to ensure dimensional tolerance. Due to the low heat capacity of magnesium alloy, compared with the production of the same aluminum alloy casting, the production efficiency is 40% to 50% higher, and the casting size is stable, high precision, and good surface finish.

2. Magnesium alloy has excellent machinability. Magnesium alloy is the most easily machined of all the commonly used metals. High cutting speed and cheap cutting tools can be used in processing, tool consumption is low. And without grinding and polishing, a very smooth surface can be obtained with cutting fluid.

DOME METALS CO., LTD. is located in Zhengzhou, the capital city of Henan Province in central China, with convenient transportation and superior geographical location. It is a modern enterprise specializing in R&D, production and sales of magnesium alloy products. Production and operation of magnesium powder, rods, plates and other magnesium products for more than 10 years before 2015, and then industrial adjustment and asset reorganization according to market demand. In 2015, a production plant mainly composed of magnesium alloy deep-processed products and magnesium plates was completed. In 2017, a magnesium alloy welding wire production line was invested and a magnesium alloy welding wire-based production plant was established. After research and development, the factory has obtained a number of technical patents. Dome Metals was established in 2018 to specialize in expanding overseas markets. Become a qualified supplier of military industry in 2019, carry out research and development and production of military and electrical products.
