The thermal and electrical conductivity of magnesium and its melting point are very similar to those of aluminum. Whereas aluminum is attacked by alkalies but is resistant to most acids , magnesium is resistant to most alkalies but is readily attacked by most acids to liberate hydrogen (chromic and hydrofluoric acids are important exceptions).
Magnesium Ignot Magnesium metal, characterized by small density, high specific strength and specific stiffness, excellent electrical and thermal conductivity, good damping and electromagnetic shielding performance as well as excellent processing performance, has been widely used in automobile, aerospace, electronic communiions and other fields.
Magnesium is a strong, silvery-white, lightweight metal, which is used to create alloys with zinc, lead, aluminum, and other nonferrous metals. Magnesium alloys are light and feature superior machinability and ease of casting.They are often anodized to enhance their corrosion resistance.The consumption of magnesium alloys has increased considerably in recent years. This trend is progressing […]
2019/6/27· Electrical conductivity is the reciprocal quantity of resistivity. Conductivity is a measure of how well a material conducts an electric current. Electric conductivity may be represented by the Greek letter σ (sigma), κ (kappa), or γ (gamma).
Copper is the standard by which electrical materials are rated and conductivity ratings are expressed as a relative measurement to copper. These ratings will frequently be expressed as "28 IACS". IACS is the abbreviation for International Annealed Copper Standard and the nuer preceding "IACS" is the percentage of conductivity a material has relative to copper, which is considered to be 100%
