Bronze Bar Stock — Quick Reference (Alloy Grades)
Bronze bar stock is the workshop material for bearings, bushings, valve components, wear plates + precision parts requiring corrosion resistance, low friction, dimensional stability. Selection turns on alloy grade matched to service: phosphor (general bearing), aluminium (high-strength), silicon (machinability), lead (free-cutting).
| Alloy Grade | Common Designation | Best For |
|---|---|---|
| Phosphor Bronze | C93200 / SAE 660 / CDA 932 | Plain bearings + bushings — standard engineering bronze |
| Aluminium Bronze | C95400 / CDA 954 | High-strength bearings + heavy-load + corrosive service |
| Silicon Bronze | C65500 / CDA 655 | Free-machining + corrosion-resistant — instruments, marine |
| Lead-Tin Bronze (Free-Cutting) | C93800 | Easy-machining bearings — high-volume production |
| Manganese Bronze | C86300 | High-strength shafting + propellers + heavy loads |
| Tin Bronze (Gun Metal) | C90300 | Marine valves + fittings — chloride-resistant |
| Beryllium Copper | C17200 | Spring + electrical contact + non-sparking tools (mining) |
Profile types: Round (most common — bearings/bushings turned to size) | Hex (workshop tooling + spanner-grippable parts) | Flat (wear plates + shims). Self-lubricating bronze: oil-impregnated PB and SAE 841 sintered bronze — pre-loaded with oil at manufacture, lubricates at running temperature. Critical: bronze alloys vary 10× in cost — match grade to application. Companion: raw materials, key steel, tool steels, bushings.
Bronze Bar Stock
Bronze bar stock is a machining material widely used for manufacturing plain bearings, bushings, valve components, wear plates, and precision parts where corrosion resistance, low friction, and dimensional stability are required. Unlike ferrous materials, bronze machines cleanly, has self-lubricating properties in some alloy grades, and performs well in applications involving sliding contact, marine exposure, or corrosive environments. AIMS Industrial supplies bronze bar stock in round, hexagonal, and flat profiles to workshops and machine shops across Australia.
Bronze Alloy Grades
Different bronze alloys are suited to different service conditions. The most common grades used in engineering applications are:
- Phosphor bronze (C93200 / SAE 660): The standard engineering bronze for bearing and bushing manufacture. Excellent machinability, good load capacity, and strong corrosion resistance. The go-to grade for general bearing applications where plain bearings are being made to order.
- Leaded bronze: Higher lead content improves machinability and provides enhanced embedded lubricity. Suited to applications with intermittent lubrication or where the bearing will run with minimal lubricant film.
- Aluminium bronze: Higher strength and excellent corrosion resistance — particularly in marine and saline environments. Used for marine hardware, pump components, and high-load bearing applications where standard phosphor bronze lacks sufficient strength.
- Silicon bronze: Good weldability and corrosion resistance. Used in marine fastener and fitting manufacture where a weldable bronze is required.
Available Profiles
AIMS supplies bronze bar in the three most practical profiles for machining operations. Round bar is the standard starting material for bearing and bushing manufacture — the round cross-section minimises material waste when turning to size. Hex bar suits production of bolt-on components, valve parts, and hydraulic fittings where wrench flats are required. Flat bar suits wear strips, slide plates, and components machined from a flat profile.
Cutting and Machining
Bronze machines excellently with HSS and carbide tooling. Sharp tools, adequate cutting fluid, and positive rake angles produce clean finishes with minimal burring. Bronze is non-sparking, which is an advantage when machining in environments where flammable dust or vapour may be present. Material can be cut to length from stock bar using a bandsaw or cold saw — power hacksaws can be used for lighter cuts but produce a rougher finish that requires more machining allowance.
