Copper and copper alloys are essential materials in engineering, industrial, electrical, marine, decorative, automotive, aerospace, and architectural applications, offering a wide range of mechanical strength, corrosion resistance, conductivity, and formability. Our comprehensive copper alloy guide covers a full spectrum of alloys, including brass (H59, H62, H65, H68), bronze (H80, H90, H95), electrolytic copper (C11000), oxygen-free copper (C10200), copper-nickel (C14500, C71500), nickel silver (C70600, C75200), and specialty copper alloys for precision and industrial use.
These copper alloys are available in multiple forms such as sheets, plates, strips, foils, bars, rods, tubes, pipes, wires, and extrusions, supplied in compliance with GB/T, ASTM, EN, ISO, and JIS standards. Whether you are sourcing high-conductivity copper for electrical wiring, marine-grade CuNi for heat exchangers, wear-resistant bronze for bushings and bearings, decorative nickel silver for musical instruments or architectural hardware, or standard brass for plumbing and fasteners, this guide helps global buyers, engineers, and importers quickly compare alloys, select the correct grade, and ensure performance for your application.
