The Oprey range of copper thermal spray alloys includes:

Self bonding alloys
Flame spraying and metallizing alloys

Self bonding copper alloys

Self bonding copper alloy with optimum characteristics for applications where a single metallized coating is preferred. With adequate surface preparation and suitable thermal spraying equipment, high density coatings are produced with high bond strengths. For corrosive environments, the deposit will require a sealant. ≥

Alloy	Cu	Cr	Ni	Al	Fe	Mo
SB 85	Bal.	-	-	10.0	3.0	-

Flame spraying and metallizing copper alloys

Gas atomized metal powder suitable for flame spraying or metallizing, without subsequent fusion of the coating. Good surface preparation is fundamental to the success of this process and the application of a bond coat (SB 80) is recommended.

Selected copper alloys for flame spraying or metallizing incl. chemical composition (nominal), %
Alloy	Description	Cu	Al	Fe	Ni
AB 1	Aluminium bronze	Bal.	9.5	2.5	1.0
AB 2	Aluminium Ni/Fe bronze	Bal.	9.5	4.5	5.5
Cu 100	Pure copper	99.90	-	-	-

Cold spray copper alloys

High purity copper powder with low oxygen content where high thermal and electrical conductivity in the coating is required.
