Bronze Parts FAQ
What bronze alloys do you work with?
We machine SAE 660 (C93200 bearing bronze — the most common, excellent self-lubricating properties), aluminium bronze (C95400 — superior strength and corrosion resistance), phosphor bronze (C51000 — excellent fatigue resistance), silicon bronze (C65500 — high corrosion resistance, low friction), and manganese bronze. Material selection depends on load, speed, and environment.
What are the advantages of bronze for bearings?
Bronze offers: natural self-lubricating properties (lead content in SAE 660), high load-carrying capacity, low friction and noise, excellent corrosion resistance (especially in seawater), superior machinability compared to steel, and the ability to dissipate heat efficiently. Bronze bearings require no external lubrication and typically outlast steel bearings.
What tolerances can you hold on bronze parts?
Bronze machines cleanly with good dimensional stability. We routinely hold ±0.02mm on general dimensions and ±0.01mm on critical bearing bores. Bore tolerances can achieve H7 fits for tight sliding or rotating applications.
Can you manufacture bronze parts for marine applications?
Yes. Aluminium bronze and phosphor bronze are ideal for marine environments — superior corrosion resistance to saltwater without special coatings. We manufacture propeller shaft bushings, seawater pump bearings, and other subsea components. Material certifications are available for marine applications.
What is the typical lead time for bronze parts?
Bronze parts typically ship within 7–12 business days. Standard material is usually in stock. Lead time includes CNC machining, inspection, and packaging. Expedite options are available for urgent requirements.
How does bronze compare to brass for wear applications?
Bronze (copper-tin alloy) has higher strength and load capacity than brass (copper-zinc). Bronze is self-lubricating and ideal for high-speed bearings. Brass is easier to machine and lower cost, but bronze is preferred for applications requiring durability and low friction. Choose bronze for critical bearing and wear applications.
