is Bronze 954?

Bronze 954 in CNC Machining

Bronze 954 is a high-strength aluminum bronze alloy with excellent wear and corrosion resistance.

It is composed of copper (Cu), with a minimum concentration of 83.0%. It also contains iron (Fe) within the range of 3.0-5.0%, aluminum (Al) at 10.0-11.5%, nickel (Ni) up to a maximum of 1.5%, and manganese (Mn) with a maximum limit of 0.50%. When machining Bronze 954 using CNC processes, we consider specific parameters to achieve optimal results. These parameters may include cutting speeds, feed rates, tool selection, and coolant usage. Bronze alloys, in general, can be machined effectively with appropriate cutting tools, and the right CNC programming can ensure precision and efficiency.

Bronze 954 has impressive tensile strength, yield strength, and ductility. It also has good welding and machining properties. This alloy is very hard and resistant to abrasion but lacks effective anti-seizure properties. It needs reliable full-film lubrication to prevent metal-to-metal contact and potential scoring. It is commonly used in manufacturing bearings, gears, valves, wear strips, and plates. 954 Aluminum Bronze and similar continuous cast bronze products like 932 and 959 are intentionally cast oversized to accommodate precise finish machining.

What is Bronze 954?

Bronze 954, designated as UNS C95400, is a widely used copper alloy known for its balanced physical and mechanical properties.

One key advantage of bronze 954 is its exceptional corrosion resistance. The aluminum content forms a protective oxide layer on the surface, preventing further moisture intrusion and slowing down corrosion. Elements like nickel and manganese further enhance its corrosion protection.

This alloy is commonly available in various forms, including flat bar, hollow rod, and solid rod, and has been used in constructing large nonferrous structures.

FAQ

Is Bronze 954 magnetic?

No, Bronze 954 is not magnetic. It is a non-ferrous alloy composed mainly of copper, aluminum, iron, and nickel. Non-ferrous metals, like copper-based alloys, do not exhibit magnetic properties.

Is Bronze 954 ductile?

Yes, Bronze 954, also known as aluminum bronze, has good ductility and malleability. Ductility refers to the ability of a material to undergo significant plastic deformation before rupture or fracture.

Can you weld Bronze 954?

Yes, Bronze 954 can be welded, but it requires careful consideration and appropriate welding techniques. Welding processes like gas tungsten arc welding (GTAW or TIG), gas metal arc welding (GMAW or MIG), and oxyacetylene welding can be used. It's important to follow proper pre-weld and post-weld procedures to ensure the integrity of the welded joint.

Can you heat treat Bronze 954?

Bronze 954 is generally not heat-treated for hardening purposes, as it is a precipitation-hardening alloy. However, it can undergo an annealing process to relieve stress or enhance machinability. Annealing involves heating the material to a specific temperature and then slowly cooling it.
