-67.63%C51000 phosphor bronze (UNS C51000, ASTM B103 / B139) is a copper alloy with about 5% tin and a little phosphorus. It is strong, withstands wear and fatigue, resists corrosion even in marine environments and conducts electricity. That is why it is used for thrust washers, bushings, wear plates, contacts and connectors. At PREMSA we CNC mill and turn it from your file, starting at a single part with an instant price.

What people ask most about C51000 phosphor bronze parts: what it is, why it is called phosphor bronze, composition, uses, machining, wear, conductivity, magnetism, corrosion, welding, equivalents, price and tolerances.
C51000 phosphor bronze is chosen for parts that slide, carry loads or conduct current and work in wet environments: thrust washers, bushings, wear plates, contacts and connectors.
At PREMSA Industries we machine C51000 with CNC milling and turning from your file, from a prototype to production.
C51000 is chosen when the part has to slide, carry load or conduct without wearing or corroding.
If your drawing doesn’t specify tolerances, we machine to ISO 2768-m (medium). On dimensions you call out —diameters, thicknesses, grooves and fits— we can hold ±0.025 mm (±0.001 in), and critical dimensions are checked in inspection.
C51000 is machined with CNC milling, CNC turning, drilling and tapping. It is hard and tough, so it is run with sharp tooling and moderate feeds to protect the finish on sliding faces.
Because it withstands wear, resists corrosion and conducts, C51000 is used in many parts made with CNC machining.
C51000 is usually the right choice when the part slides, carries load or conducts and works in a wet environment.
