A352 LCC vs LCB — frequently asked

Is A352 LCC stronger than LCB?

Yes. A352 LCC has a typical yield strength of 315 MPa (45.7 ksi) against 285 MPa (41.3 ksi) for LCB — about 11% more. Tensile strength is 525 MPa (76.1 ksi) vs 500 MPa (72.5 ksi).

Which is cheaper, A352 LCC or LCB?

Both sit in the same relative cost tier ($$, standard); the part price will be decided by machining time, tolerance and quantity rather than by the material.

Which is easier to machine, A352 LCC or LCB?

A352 LCC, by a small margin. Both rate good for machinability — 63/100 against 58/100 for LCB.
