Piano Wire Rod Introduce

Piano wire is used for small springs and has high tensile strength and fatigue life. Piano wire springs can withstand high load stress better than most other spring steels and is ideal for cyclic applications. It can be plated after forming. Piano wire meets JIS G3522 G3502 standards.

Piano Wire Rod For Clients

Use high carbon steel alloy music wire for applications that demand high strength and durability, such as springs, jewelry and piano and guitar strings. Piano wire can withstand high tension and rugged use and still last a long time. Also find spring steel in smaller thicknesses to help fabricate lockpicks, spring clamps, antennas, and small aircraft landing gear. For high-quality music wire in a variety of thicknesses and tensile strengths.
