U.S. sourcing overview
CuZn40Al2 and CuZn37Mn3Al2PbSi are designations encountered for complex high-strength brass products. A designation alone does not define every purchasing requirement. The governing standard, product form, delivery condition, dimensions and acceptance criteria must be stated on the enquiry.
Product forms and sourcing
Sourcing can be reviewed for sheet, strip, plate, tube and cut blanks, subject to grade, dimensions and quantity. Include thickness or wall, width, outside diameter, length, temper or condition, surface finish, edge requirements, straightness and any cutting or machining allowance.
Evek LLC reviews each requirement against the requested grade, specification, form, dimensions and quantity. Availability, origin, production route, minimum quantity and certification are confirmed during quotation; website text is not a stock or compliance guarantee.
Specification and substitution
The two designations should not be treated as universally interchangeable without reviewing the applicable standard. Composition limits, mechanical properties, dimensional tolerances and product-form requirements can differ. The purchaser or responsible engineer must approve any substitute.
The purchaser remains responsible for material selection, design approval and confirmation that the specified material is suitable for the finished component, manufacturing process and service environment.
Information required for a quote
Provide the exact grade, standard and revision, sheet, strip or tube requirement, dimensions, condition, quantity, tolerances, surface and edge requirements, testing, material test report, marking, permitted alternatives and U.S. delivery ZIP code.
