Lead-Free Bronze
C89833 — Lead-Free Bronze
A lead-free cast copper alloy considered for fittings, flanges and valve parts where lead content in wetted components is restricted.
Grade overview
C89833 belongs to the family of lead-free cast bronzes developed to replace leaded alloys such as C83600 in applications where lead content is restricted – notably in potable-water and similar services. Machinability in these alloys is achieved through additions other than lead.
Whether a particular casting meets a drinking-water requirement depends on the applicable regulation, the exact composition, the product design and any third-party certification. This site does not claim compliance with any such scheme; those details must be verified with the company and the end-use regulator.
Alloy family and identification

Typical composition
Composition limits for C89833 are not reproduced here pending technical review against the current edition of the applicable specification. They will be added once verified.
Reference data only – typical or nominal values from published specifications, not a guarantee of supplied material. Confirm against the current edition of the applicable specification, the product form and condition, and the material test certificate. Technical review by the company is required before publication or reliance.
Typical mechanical properties
Mechanical property values are intentionally not published here. They vary with specification, product form, size and temper or condition and will be added only once the governing specification and condition are confirmed. Request the applicable specification or test certificate with your inquiry.
Physical properties
Physical properties (density, thermal and electrical data) are not listed until verified against an authoritative datasheet. Contact us for current reference data.
Corrosion and wear considerations
Generally intended for water-handling services; actual performance depends on water chemistry, temperature, velocity and design. Lead-free alloys are not automatically interchangeable with leaded alloys for corrosion or machining performance.
Machinability and fabrication
Designed to machine acceptably without lead; machinability differs from leaded alloys, so tooling and speeds should be reviewed. Casting soundness and pressure tightness are central to this grade’s use in fittings.
Common industrial applications
- Lead-restricted water fittings and flanges
- Valve bodies and components
- Plumbing and fluid-handling hardware
- Instrumentation and manifold parts
Examples only. Suitability must be confirmed for the actual operating environment.
Available product forms
Sizes, tolerances and stock are not published and must be confirmed with the company.

Frequently asked questions
Does C89833 meet NSF/ANSI 61 or 372?
This website makes no certification claim. Compliance depends on the product and any third-party listing, which must be confirmed directly with the company.
Can I swap C89833 for C83600?
Not automatically. Properties, casting behaviour and dimensions should be reviewed against your specification.
