2024-T3 Vs T4. Good machinability and surface finish capabilities. 2024 t3 aluminum sheet has same characteristics as tubing, however, the sheet is alclad for corrosion resistance.
And when they are able to source it, it is very expensive. T3 is an alloy of the same composition that has been furnace solution heat treated, quenched to room temperature, and.
And When They Are Able To Source It, It Is Very Expensive.
For the 2024 alloy, the nominal composition is 4.4%cu, 0.6% mn, 1.5% mg, in an aluminum matrix.
Alclad Is A Metallurgically Bonded Aluminum Or Aluminum Alloy Coating That Is Anodic To The Core, Thus Electrolytically Protecting The Core Against Corrosion.
Solution heat treated and then cold worked.
So It Would Appear That If You Can Use 2024 T3 You May Not Have To Heat Treat.
