GLIDCOP® is manufactured in three different grades:

• AL-15 (UNS-C15715)
• AL-25 (UNS-C15725)
• AL-60 (UNS-C15760)

In the production of GLIDCOP® mill forms, GLIDCOP® powder is placed inside pure copper cylinders and subsequently consolidated to full density. In this process, the pure copper cylinder becomes an integral part of the final product. The GLIDCOP® product is actually a composite that includes a GLIDCOP® inner core,  encased in an oxygen-free copper outer “cladding.” Some applications require removal of the copper cladding from the GLIDCOP® to meet specific design or application requirements. Cladding thickness will usually represent 8-12% of the total GLIDCOP® cross section. It is generally recommended to remove 20% of the material cross section by milling, turning or grinding to assure complete removal of this copper cladding.

All available grades of GLIDCOP® (AL-15, AL-25, and AL-60) can be provided in the “LOX”, or Low Oxygen grade, for applications requiring exposure to elevated temperatures in hydrogen-containing atmospheres or vacuum. GLIDCOP®-clad products are not recommended for these types of elevated temperature environments.
