Abstract: A copper-aluminum alloy flame spray powder is provided consisting essentially by weight of 0 to about 5% Fe, about 2% to 8% Ni, about 5% to 15% Al, and the balance essentially copper, a coating produced from said powder being characterized by improved as-sprayed hardness in combination with resistance to oxidation and galling.

Abstract: A filler metal composition and method are provided for producing strong brazed joints between metal parts, e.g. steel parts, assembled in joint-forming relationship with each other, the filler metal comprising an indium-containing silver brazing alloy consisting essentially by weight of about 30% to 70% Ag, about 3% to 20% In, about 3% to 20% Zn, up to about 0.5% Si and the balance essentially copper.

Abstract: A multi-component metal coating consumable is provided in the form of a rod comprised of two different rod portions coaxially butt joined together in end-to-end relationship, one of said rod portions being a composite consisting essentially of at least 10% by weight of coarse particles of a refractory carbide dispersed through an alloy matrix, the other of said rod portions comprising a compatible alloy matrix structure, such that a welding or brazing rod is provided having two working ends, one to augment the other during the application of a hard and wear resistant coating to a metal substrate.

Abstract: A filler metal composition and method are provided for producing strong brazed joints between metal parts, e.g. steel parts, assembled in joint-forming relationship with each other, the filler metal comprising an indium-containing, low silver, copper base brazing alloy consisting essentially by weight of about 0.5% to 15% Ag, about 1% to 14% In, about 50% to 85% Cu, up to about 0.6% Si and the balance essentially zinc.
