Types of Aluminum Heat Treatments - L&L Special Furnace Co ...

Aluminum heat treatment is a process by which the strength and hardness of a specific subset of aluminum alloys, namely the wrought and cast alloys that are precipitation hardenable, are increased. Precipitation hardenable aluminum alloys include the 2XXX, 6XXX, 7XXX and 8XXX series. In addition, annealing may be required for parts that have ...

A second advantage of LPC is cleanliness of the parts after processing. The finished parts emerge from the furnace very clean. At times it is almost difficult to identify the heat-treated and non heat-treated parts. For this reason the heat-treated parts are slightly discolored, using the discoloration process to identify the heat-treated parts.
