Silicon bronze is popularly known as simply bronze material, and regularly finds use in marine applications. We produce Silicon bronze fasteners, which is 95%-98% copper, plus a small amount of silicon to add strength. We mainly manufacture a wide range of brass, bronze (silicon bronze, phosphor bronze, aluminium bronze) fasteners in accordance with ASME, ANSI, DIN, EN, ISO standards as well as according customers’s drawing or sample. Silicon bronze is non-magnetic and is has a high degree of thermal conductivity. It also has high corrosion resistance and can be used in harsh environments such as salt water and gases. Silicon bronze is only a low conductor of electricity.

We are a professional factory for manufacturing nickle alloy and superalloy fasteners. As a high technology alloy manufacturer, we can produce bolts, nuts, studs/threaded rods, screws according to ASME/ASTM/DIN standard and specifications. We have different kinds of standard & non-standard fasteners made from Hastelloy Alloy, Monel Alloy, Nickel Alloy, Inconel Alloy, Incoloy Alloy, Precipitation Hardening Steel, Anti-corrosion Alloy, Duplex Stainless Steel, Superalloy, Precision Alloy, Austenitic Stainless Steel.
