Softening Copper Sheet

Fill the basin up with cold water and set it near your work station.

Softening copper sheet.

The easy test to see if it has softened is to tap it with a screwdriver or something similar. For example you may only need to heat a thin jewelry grade piece of copper for 20 seconds to anneal it. Once this occurs quickly immerse the copper you are annealing into a water bath and that s it. 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.

110 copper sheet plate is widely known for its architectural applications whereas the familiar green patina appearance is acheived when exposed to the elements copper sheets and plates have excellent hot or cold workability and is ductile when heated. Hold the copper firmly. In brasses bronzes nickel silvers copper nickels and other alloy families strength is increased in proportion to the amount of cold work. The copper most commonly used for sheet and strip applications complies with astm b370.

Our c11000 copper is 99 90 pure copper and 04 oxygen for hard drawn sheet and plate offering high thermal and electrical conductivity with low ground resistance. Storm s copper sheet is manufactured to the astm american society for testing and materials b187 b152 and b283 09 specification standards for copper and copper alloy. The annealing process can work to soften any piece of copper regardless of its thickness or size. At basic copper we sell pure copper c110 other alloys and tempers available upon request.

Adjust the flame on the torch so it s an inch to 2 inches long. However the amount time that you ll need to heat the copper for will increase proportionately with the thickness of the copper. In general copper alloys exhibit increased strength proportional to the amount and the nature of the alloying element. If you hear a ringing sound the copper is still hard and needs to be annealed again.

Certificate of conformance provided upon request other alloys and tempers available upon request. Slowly open the valve on the propane torch. If the sound is dull then you have annealed the copper properly. These sheets are pure copper c110 99 9 pure copper.

It also comes in many alloys that blend other metals with copper. You ll need a very hot but rather gentle flame. 060 soft h00 cold rolled h01 cold rolled high yield h02 half hard h03 three quarter hard and h04 hard. How to soften copper step 1.

Copper sheets plates are also noted for their high electrical and thermal conductivity and good corrosion resistance. It consists of 99 9 percent copper and is available in six tempers designated by astm b370 as.
