Copper and Brass Rivets made in USA from certified copper and brass materials. Our copper and brass wire are made in USA by reliable manufacturers of round wire. We cold form our copper rivets and brass mandrels with carbide and high alloy tool steel tools. This manufacturing process takes place within our facility and is controlled by our very experienced team of rivet manufacturers. This manufacturer offers two lengths of 1/8″ diameter copper rivets with Brass mandrels. The 42 length is capable of gripping applications from 1/16″ thin to 1/8″ thick. The 44 length is for gripping applications from 1/16″ thin to 1/4″ thick. The 44 length is a little longer for use where applications present several layers of sheet metal or other materials. The longer length will allow the rivet to reach beyond the back side layer to assure clamping. By utilizing certified copper and brass materials this US manufacturer can assure customers these products are pure, traceable materials. These copper and brass rivets are not plated to look like copper and brass rivets, which are often sold at discounted prices to unaware buyers.
Often used by roofing installers, copper and brass rivets assure like materials when copper flashing work is installed. Don’t be fooled by bargain basement prices as they often contain copper plated rivets which will rust and potentially leave holes for water leakage in your roof. There’s one simple test to assure you’re buying copper rivets and brass mandrels. If a magnet easily picks them up, and/or you can scrap off the copper plating with a sharp edge. You are getting steel and not getting pure copper and brass rivets. Don’t buy steel rivets with copper plating as you won’t like the rusted results. When buying and installing the real copper and brass rivets you’ll enjoy many years of tightly fastened flashing without any signs of rust from inferior rivets.
North American Slate is considered the best quality slate with almost an indefinite life span when installed with the proper substrate and fasteners. Copper and brass rivets are considered among the best quality fastener for riveting the copper flashing, copper gutters and numerous architectural roofing products available to builders. The Plumbing industry utilizes copper and brass rivets in numerous applications including heat ex-changers, fixtures and bracket fasteners.
brass, alloy having copper (55%–90%) and zinc (10%–45%) as its essential components. The properties of brass vary with the proportion of copper and zinc and with the addition of small amounts of other elements, such as aluminum, lead, tin, or nickel. In general brass can be forged or hammered into various shapes, rolled into thin sheets, drawn into wires, and machined and cast. Its ductility reaches a maximum with about 30% zinc and its tensile strength with 45%—although this property varies greatly with the mechanical and heat treatment of the alloy. Cartridge, and/or Yellow brass (65 to 70% copper, 30% to 35% zinc) is used for cartridge cases, plumbing and lighting fixtures, copper and brass rivets, screws, and springs. Aluminum brass (not exceeding 3% aluminum) has greater resistance to corrosion than ordinary brass. Brass containing tin (not exceeding 2%) is less liable to corrosion in seawater; it is sometimes called naval brass and is used in naval construction. Dutch metal (80%–85% copper, 15%–20% zinc) is used as a substitute for gold leaf. When iron is added to brass it produces hard, tough alloys. One of these is delta metal (55% copper, 41% zinc, 1%–3% iron, and fractional percentages of tin and manganese), which can be forged, rolled, or cast and is used for bearings, valves, and ship propellers.
copper, metallic chemical element; symbol Cu [Lat. cuprum = copper]; at. no. 29; at. wt. 63.546; m.p. 1,083.4°C; b.p. 2,567°C; sp. gr. 8.96 at 20°C; valence +1 or +2. Copper and some of its alloys have been used by humanity since the Bronze Age. One of the first metals known to humans, copper was smelted as long ago as c. 5000 B.C. Cyprus, from which the metal’s name originally comes, was a major source of copper in the ancient world. The chief commercial use of copper is based on its electrical conductivity (second only to that of silver); about half the total annual output of copper is employed in the manufacture of electrical apparatus and wire. Copper is also used extensively as roofing, in making copper utensils, and for coins and metalwork. Copper tubing is used in plumbing, and, because of its high heat conductivity, in heat-exchanging devices such as refrigerator and air-conditioner coils.
