Soft annealed copper sheet.

For copper and brass alloy the physical process is different and the soft annealing temperature is between 300 c and 650 c for copper alloys and between 425 c and 650 c for brass alloys. Types of copper and properties the copper most commonly used for sheet and strip applications complies with astm b370. 1 mil 001 inches thick.

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. All of our raw copper sheets are pure copper annealed dead soft with a smooth commercial finish manufactured to astm b152 alloy c110. Make sure you heat the entire piece. It consists of 99 9 percent copper and is available in six tempers designated by astm b370 as.

This is very thin copper foil. You can anneal any grade and thickness of copper as long as you have a flame that can transmit enough heat to the metal. K s precision metals 6020 soft annealed copper foil 0 005 copper 36 gauge 12 width x 30 length 1 pc made in usa 4 7 out of 5 stars 40 14 18 14. It is approximately 1 5 times thicker than typical household aluminum foil and is easy to cut but also easy to wrinkle.

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. Continue to soften the copper until it changes to a red color. Soft annealing is usually performed in a furnace with protective gas or in a vacuum furnace to avoid oxidation or de carburisation. This malleability allows you to hammer and mold the copper into any shape you wish without cracking the metal.

But don t delay the quenching too much otherwise you will not achieve the annealed copper you were aiming for. 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. You can tear. Heat the copper with the propane torch by slowly moving the flame across it.

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