Bonding Copper Sheet

Signal and power bonds to railroad rails and bonds on crane rails.

Bonding copper sheet.

For copper and aluminum the bonding mechanisms are metallurgical with s bond s active nature disrupting the oxides that form on al and cu. Bonding to steel is one of the toughest types of grounding connections. Types of copper and properties. Apply a small amount of instant glue to one of the surfaces join it to the other surface and hold the pieces together for a minute.

Apply the adhesive to the areas that you wish to be bonded. Solderless copper bonding also known as cold soldering gluing copper or cold welding uses a liquid durable polymer which is applied to rigid pipe fittings to literally weld them together hermetically absolutely nothing can get in impenetrable. Press the metal pieces together firmly and use adjustable clamps to hold them in place. In a well ventilated area thoroughly wash the back side of the copper with water or acetone using a steel wool or synthetic steel wool scotch brite pad.

The copper most commonly used for sheet and strip applications complies with astm b370. 060 soft h00 cold rolled h01 cold rolled high yield h02 half hard h03 three quarter hard and h04 hard. Another option for gluing metal is loctite epoxy weld bonding compound. Do not apply the adhesive to the copper.

When it comes to copper adhesive cyberbond is the manufacturer you can depend upon. It consists of 99 9 percent copper and is available in six tempers designated by astm b370 as. Different brands of epoxy mature at varying rates but most require 24 hours curing time. Copper and its alloys are readily bonded with a variety of adhesive types.

1 grounding indoor and outdoor structures reinforcing bars rebar in concrete construction fence and gateposts steel enclosures etc. Apply the adhesive to the porous substrate with a glue roller. A convenient alternative to welding it s the strongest solution for bonding most metals including iron steel aluminum brass copper and pewter. Anaerobic adhesives cure in the presence of metal and absence of oxygen.

Our copper bonding materials can accommodate all of your copper bonding needs. Copper is a highly conductive corrosion resistant and ductile metal which is easily bonded by epoxies acrylics or cyanoacrylates offered by cyberbond. For other metals that form tenacious oxides such as stainless steel and titanium s bond bonds adhesively with no resolvable metallurgical reactions. Two applications typically require bonding to steel.

Copper is one of the most reactive metals so the anaerobic adhesive will set up and cure much more quickly than the time listed for fixture speed on steel. Gently scuff sand the back of the copper veneer with 80 or 120 grit sandpaper. Adhesives are preferred over soldering as they do not heat damage the copper.
