Available Grades
Copper or brass alloy by drawing, sample or application. Equivalent GB, ASTM, JIS or EN references can be discussed before quotation.

Product
Custom Copper Alloy Profiles for special shaped profiles, machinery parts, custom assemblies and hardware. Send grade, size, quantity and destination for quotation review.
Buyer answer
A custom copper-alloy profile cannot be reviewed from a product name alone. Send a dimensioned cross-section or a clear section sketch with the alloy requirement, datum structure and individual tolerances. Add profile length, straightness, surface and any wall-thickness note that applies to the section. If cutting, drilling, machining or another secondary operation is part of the request, distinguish it from the as-formed profile dimensions. A sample photo can clarify orientation, but the controlled drawing should identify which features and inspection points govern the quotation.
Send the section drawing, alloy reference, datums, tolerances, length, secondary-work boundary, quantity and destination for review.

Product questions
Use a controlled cross-section and clear supplied-part boundary for custom copper-alloy profile review.
Provide the complete cross-section with datums, radii, angles, wall dimensions where applicable, critical tolerances and general tolerances. Add supplied length, straightness, end condition and the designated visible surface.
Mark whether holes, slots, cutting, machining or other operations belong to the supplied profile. A sample photo can clarify orientation, but the controlled drawing should identify the measured features and inspection points.
Confirm the alloy requirement, cross-section revision, datums, tolerances, length, straightness, surface, secondary-work boundary, requested documents, shape-protective packing and commercial terms in the quotation.
Send grade, size, quantity, destination country and application for faster quotation review.
