Annealed copper sheet.

You can tear. These sheets are pure copper c110 99 9 pure copper. On the other hand copper can be softened even more than it naturally is. You may want to soften copper so you can bend it without crushing it or distorting its shape.

You can anneal any grade and thickness of copper as long as you have a flame that can transmit enough heat to the metal. In metallurgy and materials science annealing is a heat treatment that alters the physical and sometimes chemical properties of a material to increase its ductility and reduce its hardness making it more workable it involves heating a material above its recrystallization temperature maintaining a suitable temperature for an appropriate amount of time and then cooling. 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. Annealing copper makes it softer and less brittle which allows you to bend it without breaking it.

This malleability allows you to hammer and mold the copper into any shape you wish without cracking the metal. Certificate of conformance provided upon request other alloys and tempers available upon request. 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.

Work hardened materials such as sheet metal that has undergone a stamping process or cold drawn bar stock. This is very thin copper foil. 060 soft h00 cold rolled h01 cold rolled high yield h02 half hard h03 three quarter hard and h04 hard. The copper most commonly used for sheet and strip applications complies with astm b370.

These products made from copper and copper alloys may be heat treated for several purposes such as homogenizing annealing stress relieving and precipitation hardening. If you hit it repeatedly it becomes harder. It is approximately 1 5 times thicker than typical household aluminum foil and is easy to cut but also easy to wrinkle. When you anneal copper it expands and becomes soft and pliable thus giving you a seal once the copper has been compressed.

Metal wire that has been drawn from one size to a smaller size may also undergo an annealing process. Triumph 650 copper head gaskets. Typically non annealed copper head gaskets are harder to bend thus causing leaks if you install them as is. 1 mil 001 inches thick.
