Gun metal ingots are a copper-based alloy primarily composed of copper, tin, and zinc, widely used in casting applications where strength, corrosion resistance, and machinability are essential. These ingots are melted and cast into components such as pump housings, valves, gears, marine fittings, and various heavy-duty mechanical parts. Known for their excellent fluidity during casting and resistance to seawater and steam, gun metal ingots are ideal for use in marine, industrial, and engineering environments. Common compositions include variants like LG2 and LG4, offering a balance of tensile strength, hardness, and wear resistance. GK Enterprises produces high-purity gun metal ingots with consistent alloy composition, minimal slag formation, and smooth melting characteristics, ensuring clean, defect-free castings and superior machining performance. Available in multiple sizes and weights, our ingots are crafted to meet both domestic and international foundry specifications.
GK Enterprises manufactures high-quality gun metal ingots using precise alloying of copper, tin, and zinc to deliver excellent casting properties, corrosion resistance, and mechanical strength. Our ingots are widely used in marine applications, pump and valve bodies, bushings, and various engineering components due to their durability and ease of machining. Designed for consistent performance in both foundry and industrial manufacturing settings, these ingots offer smooth melting, low gas content, and minimal slag formation during processing.
