Annealing brass sheet metal.

The inside of the oven must be large enough to allow air to circulate around the piece of metal. Annealing is a heat treatment process in which the sheet metal is altered on a molecular level altering its strength and hardness. 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. For large pieces gas fired conveyor furnaces are used while car bottom furnaces are more practical for smaller pieces of metal.

Hello i have a piece of brass sheet cu 60 zn 40 15cm x 8 cm x 4mm thick. How to anneal brass.
