Aluminum Buying Guide

Bottom line: Specify alloy and temper as well as shape and dimensions. 6061 and 6063, for example, are not interchangeable simply because both are aluminum.

What to put on the RFQ

How to avoid buying the wrong material

Start with the project drawing, approved material specification or actual service conditions rather than a generic product name. Dimensions, grade/specification, finish, length, quantity, processing, certifications and delivery requirements can all change what should be quoted.

For replacement or maintenance material, photos and measurements help, but markings, mill certifications, original drawings or manufacturer information are stronger evidence when available.

Send a cleaner RFQ

Attach the drawing, cut list or material takeoff whenever possible. Include delivery ZIP and required date so sourcing and freight can be evaluated.
