Which Quote Do You Need?

Keep the Original Material
If the grade is fixed by your drawing or customer, say so. We review the quotation against that specification.
Compare a Possible Alternative
Explain whether cost, sourcing, weight or another requirement is driving the review. A candidate can be considered alongside the original grade where feasible.

Tell Us What Must Stay the Same

In use: Loads, stiffness, wear and important assembly fits.
Environment: Temperature, chemicals, moisture and corrosion exposure.
Acceptance: Tolerances, finish, appearance and required documents.

For plastics, long-term deformation under load and moisture response also need attention.

Can 6061 Replace 7075?

6061-T6 is generally lower in strength than 7075-T6. The grades are not automatically interchangeable.

For a housing or similar part, the design authority needs to confirm the loads, geometry, material condition and any validation required. A revised quote can then be reviewed.

Before You Send the Enquiry

Can you review metals and plastics?

Yes. Share the exact grade, including aluminum, stainless steel, brass, POM, ABS, PC, nylon or PEEK, together with operating conditions. Suitable candidates depend on the application.

What if I need material documents?

List required certificates, RoHS or REACH documentation and any customer specifications at quotation. Supporting evidence and the required scope need confirmation for the selected material.

Will I approve the change first?

Yes. We discuss the candidate and quote, agree any sample or testing needs, and confirm the material specification and drawing revision with you before production.
