Difference Between Aluminum Alloys 3003-H14, 3003-H18, and 3003
Aluminum 3003-H14, 3003-H18, and 3003 are all part of the same aluminum alloy family, but they differ in their temper designations.
H14 and H18 represent the temper designations of the aluminum alloy, which indicate the state of the alloy after undergoing different degrees of work hardening. The number following the letter “H” denotes the hardness and degree of processing of the aluminum alloy.
Both H14 and H18 refer to the states of 3003 aluminum alloy after cold work hardening.
H18 has higher hardness than H14, meaning H18 has higher strength but lower plasticity.
- 3003 is the alloy designation, indicating its chemical composition.
H14 and H18 are the temper designations, indicating the hardness and degree of processing.
3003-H14 and 3003-H18 are both 3003 aluminum alloy, but with different hardness levels.
