A novel laminated composite material of gold-colored appearance especially suited for, but not limited to, coinage applications has a ferromagnetic core located between sheathing layers of a Cu-Al or Cu-Ni-Al alloy and separated therefrom by layers of copper. Alternative methods involving hot and/or cold rolling techniques are provided for the production of the novel laminates.

Gold colored laminated composite material having magnetic properties

An alloy particularly directed to use as a wrought filler metal and contains certain percentages of chromium, iron, boron, molybdenum, nickel and optionally carbon, manganese and silicon.

Wrought filler metal for welding highly-castable, oxidation resistant,

A method for producing high strength composite tubing having a corrosion-resistant metal lining. The composite tubing is prepared by extrusion of an assembly having a low alloy steel outer shell and metal powder lining. The metal powder is consolidated during extrusion and high strength is attained by heat treatment.

Clad metal tubes

A highly-castable, ductile, corrosion-resistant and weldable stainless steel intended for exposure in marine environments. A highly satisfactory composition of the alloy is 24% Ni, 24% Cr, 4% Mo, 2% Si, 0.2% B and balance iron.

Highly castable, weldable, corrosion resistant stainless steel

Directed to a welding flux and covered welding electrodes, and, more particularly, to covered electrodes having a nickel-chromium-iron alloy core and a special flux coating or covering, which electrode is capable of joining similar and dissimilar metals and which produces, in all positions, sound welds free from cracking and porosity and deposits having excellent corrosion resistance.

Welding electrode

An alloy particularly suited for use as an inert gas shielded-arc filler metal containing 28% to 35% chromium, 13% to 18% iron, 2.8% to 4.2% aluminum, 0.1% to 3.8% manganese, up to 0.2% silicon, 0.3% to 0.8% titanium, 0.04% to 0.15% carbon and the balance essentially nickel. The filler provides the capability for making substantially defect-free welds in heavy section thicknesses that have excellent elevated temperature carburization resistance and strength.
