Soft Annealed Copper Sheet

If the sound is dull then you have annealed the copper properly.

Soft annealed copper sheet.

Heat the copper with the propane torch by slowly moving the flame across it. 060 soft h00 cold rolled h01 cold rolled high yield h02 half hard h03 three quarter hard and h04 hard. You can anneal any grade and thickness of copper as long as you have a flame that can transmit enough heat to the metal. It is approximately 1 5 times thicker than typical household aluminum foil and is easy to cut but also easy to wrinkle.

It consists of 99 9 percent copper and is available in six tempers designated by astm b370 as. All of our raw copper sheets are pure copper annealed dead soft with a smooth commercial finish manufactured to astm b152 alloy c110. By delaying you are normalizing the copper which means it is not soft enough to become pliable and can easily fracture if bent too rigorously. You can tear.

These sheets are pure copper c110 99 9 pure copper. They have a bare smooth commercial finish are annealed soft malleable annealed copper is much more pliable and workable than non annealed copper and manufactured to astm b152. 0216 copper in 4 x 10 sheets also sold as copper flashing these non annealed hard copper 4 x 10 sheets are shipped in a special rigid package to ensure each sheet arrives flat and in excellent condition.

Make sure you heat the entire piece. Soft annealing is usually performed in a furnace with protective gas or in a vacuum furnace to avoid oxidation or de carburisation. Certificate of conformance provided upon request other alloys and tempers available upon request. Types of copper and properties the copper most commonly used for sheet and strip applications complies with astm b370.

This malleability allows you to hammer and mold the copper into any shape you wish without cracking the metal. Annealing copper makes it softer and less brittle which allows you to bend it without breaking it.
