06. Technical Description
KUPTİN® 10 CuSn10 Tin Bronze Technical Description
KUPTİN® 10 belongs to the CuSn10 tin bronze family with approximately 10% tin. Published EN 1982 / CuSn10-C tables list Cu + Ni at 88-90%, Sn at 9-11%, Zn up to 0.5%, Pb up to 1% and Ni up to 2%. These limits should be read together with the ordered product form and the applicable project specification.
Mechanical Behaviour
Mechanical values for CuSn10-C / CC480K vary by casting method, including sand casting, permanent mould casting, continuous casting and centrifugal casting. The local CMS values of 250-280 MPa tensile strength, 130-170 MPa yield strength, 70-80 HB hardness and approximately 8.7 g/cm3 density are aligned with published reference data. They are reference values, not a universal guarantee.
Production Technology and Supply Forms
KUPTİN® 10 can be considered for centrifugal casting, continuous casting and custom cast components. The suitable production route dépends on part geometry, dimensions, machining allowance, operating load and delivery form. The preserved supply forms are round bar, flat bar/plate, tube or hollow part and custom casting.
Applications
Typical applications include bronze bushings, plain bearings, gears, worm wheels, pump parts, valve bodies, piston rings and fittings exposed to seawater. Published sources for CuSn10-C and comparable tin bronze grades such as C90700 emphasize heavy-load, low-speed, wear-resistant and corrosion-resistant service.
Standards and Comparable Grades
EN 1982 CuSn10-C / CC480K is the main verified reference for this content. BS 1400 CT1 and DIN 1705 G-CuSn10 / 2.1050.01 appear in sources as comparable former designations. ASTM B505 is not an alloy grade name; it is a product specification for continuous cast copper alloys. Sources list UNS C90700 and, in some tables, C92700 as close international comparisons for CuSn10-C. The existing CMS value C90500 has not been silently removed, but it should not be published as a confirmed equivalent without user approval and standard-level verification.
Technical Note
This package is an unpublished draft and has not been applied to the database. Technical values do not replace purchase specifications, production drawings or inspection certificates; final product values dépend on order specification, casting method, section size and quality control results.
