Why distributors stock Rearden

What matters when you hold the inventory and answer to the end customer.

One bar for two callouts

C10100 meets the C10200 chemistry, so one oxygen-free bar can serve both specifications. We certify against the grade your customer orders.

Certificates you can pass on

Every lot ships with a quality certificate from our ISO 9001 system, ready to forward with your sale.

Full lengths or cut to size

12 ft standard bars, special lengths up to 19.5 ft, and pieces cut to length under 6 ft.

A clean base for plating

Free of oxide inclusions, OFE bar is a better base for silver and tin plating.

Made in Houston, Texas

Plant pickup or delivery anywhere in the U.S. Our rod is made from U.S.-origin cathode.

Shapes and strip to order

Questions distributors ask

Not answered here? Write to sales@reardenprecision.com.

Do you sell to distributors and service centers?

Yes. If you carry inventory and supply certified material, our distributor program is built for you, and our sales team will set it up with you.

Can C10100 replace C10200 in my stock?

Yes. C10100 is the tighter grade: 99.99% copper and 5 ppm oxygen maximum, against 99.95% and 10 ppm for C10200. It meets the C10200 chemistry, and we certify against the grade your customer specifies.

Is C10100 the same as OFHC copper?

OFHC is a common trade name for oxygen-free, high-conductivity copper. C10100, also called OFE, is the highest-purity oxygen-free grade, and it also meets the C10200 chemistry. See the grade comparison.

What comes with each shipment?

A quality certificate for the lot, issued under our ISO 9001 quality management system, with results from the melt to the finished product.

Which lengths and sizes can I order?

Standard length is 12 ft. Custom lengths from 10 to 19 ft are available upon request.
