COPPER ALLOY 101/102/103
Our current inventory stocks the Copper alloy 101 and other oxygen-free alloys as well. We welcome any opportunity in Copper you may require in the foil and sheet gauges. Additionally, we stock Copper Foil and Copper Sheet metal in thicknesses of 0.004 to 0.100 inches in a variety of tempers. Our copper slitting capabilities range from the narrowest of 3/8th inch wide on all items and as wide as 36 inches wide in certain copper foil gauges. In most cases, our Copper stock is 24 inches wide on all other gauges.
Comet Metals Inc carries a wide variety of specialty metals in an assortment of alloys, gauges, widths, tempers and coil sizes. We pride ourselves on fast service, dependability and quality products, at the right price!
