Waterproof High Pure Smooth Magnesium Metal Sheet Etching For Photoengraving

The waterproof high-purity smooth magnesium alloy sheet is engineered for etching and photoengraving applications. Its smooth, fine surface ensures fast and uniform heat transfer, delivering flatness and large-area consistency that zinc and copper plates cannot match. This makes it an essential material for high-quality bronzing, hot stamping, embossing, and other printing and packaging processes.

The rolled magnesium alloy engraving plate is produced from semi-continuous casting magnesium alloy ingots, extruded on a 10,000-ton press, then heated in an equalizing furnace and leveled. Through grain refinement and recombination, the resulting plate offers the inherent lightweight properties of magnesium alloy (density 1.74 g/cm³ — only 2/3 that of aluminum, 2/5 of titanium, and 1/4 of steel). Magnesium alloy is 36% lighter than aluminum alloy, 73% lighter than zinc alloy, and 77% lighter than steel. It also provides excellent plasticity, very low thermal expansion and prestress, and vibration performance 30 times higher than aluminum. These characteristics extend mold life across repeated use, making it the preferred material for metal molds.
