6162 is also supplied in 8 other conditions. The full side-by-side table is on the 6162 overview.
- T651Use when low residual stress and dimensional stability during heavy machining are required at T6 strength.265 MPa yield · 95 HB
- T6Standard stocked condition: peak-strength temper for structural profiles, tube and machined parts.262 MPa yield · 95 HB
- T5511Same as 6162-T5510 but a minor straightening pass after stretching is permitted, giving tighter straightness tolerances at essentially identical mechanical properties.240 MPa yield · 82 HB
- T5Most economical aged temper for press-quenched profiles where T6 strength is not required and distortion must be minimal.240 MPa yield · 85 HB
- T55106162 extrusion aged directly from the press (T5) then stretched to relieve residual stress, with no subsequent straightening — dimensionally stable bar/profile at near-T5 strength.235 MPa yield · 80 HB
- T4Choose for parts that must be bent/formed after heat treatment and can be artificially aged (to T6) later.110 MPa yield · 60 HB
- OPick when maximum ductility for bending/forming is needed and the part will be re-heat-treated afterwards.60 MPa yield · 32 HB
Working with 6162-T5
Is 6162 easy to machine?
Machines well in T5/T6 with sharp polished tools, high speed and generous coolant; gummy and prone to built-up edge in O/T4 — use high rake and chip-breaking geometry.
Can 6162 be welded?
Readily GTAW/GMAW welded with 4043 (crack resistance) or 5356 (strength/colour match); HAZ drops to near-T4 strength unless re-solution treated and aged.
Can 6162 be formed, bent or molded?
Extrudes easily and can be press-quenched to T5; bend and roll-form in O or T4 and age afterwards, since T6 has limited cold bend radii.
What surface finishes work on 6162?
Takes clear, hard and coloured anodizing well, plus conversion coating, powder paint and mechanical polishing; degrease and etch before anodizing to avoid Mg-rich streaks.

6162-T5 — frequently asked
What is 6162-T5 used for?
6162-T5 is typically used for auto fittings, hydraulic manifolds and connectors. In short: free-machining variant.
What is the yield strength of 6162-T5?
6162-T5 has a typical yield strength of 240 MPa (34.8 ksi) and a tensile strength of 265 MPa (38.4 ksi) — stronger than 62% of aluminum grades. Strength varies by condition: see the 9 listed tempers.
Is 6162-T5 easy to machine?
Reasonably — machinability is rated good (62/100, better than 55% of aluminum grades). Machines well in T5/T6 with sharp polished tools, high speed and generous coolant; gummy and prone to built-up edge in O/T4 — use high rake and chip-breaking geometry.
Can 6162-T5 be welded?
Yes — weldability is rated very good (80/100). Readily GTAW/GMAW welded with 4043 (crack resistance) or 5356 (strength/colour match); HAZ drops to near-T4 strength unless re-solution treated and aged.
What surface finishes work on 6162-T5?

Can 6162-T5 be formed, bent or molded?
Extrudes easily and can be press-quenched to T5; bend and roll-form in O or T4 and age afterwards, since T6 has limited cold bend radii.
What is the maximum service temperature of 6162-T5?
6162-T5 is rated for continuous use to about 150°C (302 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
