TIG welding (plus)
Place Mg in a slightly alkaline solvent, remove surface oxide membrane, fingerprints etc.
Next place in a water solution and finally bake. This hardens the surface membrane.
Because the membrane coats the crystals on Mg evenly, unlike normal treatment methods,
it is possible to prevent corrosion. Also, this membrane cuts infra-red radiation and
prevents color change in the metal materials keeping their original condition as well as making staining from finger prints and dirt easier to remove.
Because there is a surface strength of gover 8h the materials can withstand a certain degree of shock. Temperature resistance is approximately 200\250.
1.Mg is the lightest of practical metals and has 2/3 the specific gravity of aluminum and 1/4 that of iron.
2.Mg has the greater specific strength than iron or aluminum.
3.Mg has the greatest vibration absorption of industrial metals
4.Easy cutting and sag resistant.
5.There is little change to dimensions even if temperature or time periods are changed.
