How to find the right Bronze Bars AI guide
Written by an AI model from its trained knowledge.
What the AI looks for in Bronze Bars
- Alloy for the job
- C93200 (SAE 660) for general bearing and wear plates. C95400 aluminum bronze for heavy loads and high wear. C51000 phosphor bronze for springy or corrosion-resistant flat parts. C65500 silicon bronze for marine and weldable fabrication. These alloys differ widely in strength, machinability and corrosion behavior, and the wrong one wears or fails early.
- Cast vs wrought
- Continuous-cast bearing bronze flat bar is usually supplied oversize with a machining allowance. Wrought or drawn bar is held closer to the nominal size. Cast bar has to be machined to final size, so do not plan to use its as-supplied faces as finished surfaces.
- Lubrication regime
- Use oil-impregnated sintered bronze (SAE 841 type) only where re-oiling is impractical and loads are moderate. Use solid cast bronze where grease or oil is supplied. Sintered bar is self-lubricating but weaker, and heavy machining smears and seals its pores.
- Lead content
- Avoid leaded alloys like C93200 and C54400 for potable water or food contact. Lead helps machinability and bearing performance but is not acceptable in contact with drinking water or food.
Brands that matter
- Concast: Major US producer of continuous-cast bronze bar in bearing and aluminum bronze alloys.
- National Bronze & Metals: Supplier specializing in bearing bronze and aluminum bronze bar stock.
- Bunting Bearings: Makes cast bronze bar stock and powdered-metal bearing bar.
- Oilite: Original oil-impregnated sintered bronze bar stock.
What to avoid
- Listings with no UNS alloy number or temper.
- Running a cast bronze wear strip dry. It needs a lubricant.
- Heavy machining or grinding of oil-impregnated bar surfaces.
