basic information
Stainless steel wire (SUS304WPB) is excellent in rust and heat resistance, making it suitable for outdoor and humid environments. However, its strength is lower compared to piano wire, and it is more expensive. - Wire diameter ranges from 0.16mm to 2.0mm with 23 sizes - Outer diameter ranges from 1.4mm to 24mm with 32 sizes - Free length ranges from 3mm to 200mm with 32 sizes Piano wire (SWPA) is similar to iron and rusts easily, so standard products are coated with anti-rust oil on the surface. It has about 10% higher strength compared to stainless steel wire and is less expensive. - Wire diameter ranges from 0.35mm to 4.0mm with 20 sizes - Outer diameter ranges from 2.6mm to 35mm with 32 sizes - Free length ranges from 4mm to 200mm with 43 sizes For each wire diameter, the table shows outer diameter on the horizontal axis and free length on the vertical axis, so the intersection of outer diameter and free length represents one product. *We will send you the catalog for free upon request.
