Galvanic Potential (seawater, vs SCE)-0.69 V
Corrosion ResistanceFair38/100
Chemical Resistance SummaryGood in neutral atmospheres and most organic media; attacked by strong acids and alkalis, and copper content makes it susceptible to pitting/intergranular attack in chloride environments — always painted, e-coated or clad in service.

Sustainability4

Producing a kilogram of 2036 T4-PB takes about 205 MJ of energy and emits 12.5 kg of CO₂ — more than 76% of aluminum grades. Typical recycled content is 25%.

Working with 2036 T4-PB

Is 2036 easy to machine?

Machines cleanly in T4 with sharp carbide/PCD tooling, high speed and flood coolant; chips are short and non-gummy compared with 5000-series sheet.

Can 2036 be welded?

Fusion welding is not recommended (hot cracking, loss of aged strength); join by resistance spot welding, self-piercing rivets, clinching or structural adhesive.

Can 2036 be formed, bent or molded?

Designed for cold stamping in the T4 condition — draw promptly after solution treatment while natural aging is incomplete, allow generous bend radii and expect springback higher than steel.

What surface finishes work on 2036?

Use chromate-free/phosphate pretreatment plus e-coat or paint; anodizing gives only a dull grey copper-affected film and clear decorative anodizing should be avoided.

2036 T4-PB — frequently asked

What is 2036 T4-PB used for?

2036 T4-PB is typically used for automotive outer body panels, hoods and fenders and formed sheet parts. In short: most formable 2000-series sheet; autobody panel alloy; bake-hardening sheet grade.

What is the yield strength of 2036 T4-PB?

2036 T4-PB has a typical yield strength of 245 MPa (35.5 ksi) and a tensile strength of 365 MPa (52.9 ksi) — stronger than 64% of aluminum grades. Strength varies by condition: see the 4 listed tempers.

Is 2036 T4-PB easy to machine?

Yes — machinability is rated very good (70/100, better than 72% of aluminum grades). Machines cleanly in T4 with sharp carbide/PCD tooling, high speed and flood coolant; chips are short and non-gummy compared with 5000-series sheet.

Can 2036 T4-PB be welded?

With care — weldability is rated fair (35/100). Fusion welding is not recommended (hot cracking, loss of aged strength); join by resistance spot welding, self-piercing rivets, clinching or structural adhesive.

What surface finishes work on 2036 T4-PB?

Use chromate-free/phosphate pretreatment plus e-coat or paint; anodizing gives only a dull grey copper-affected film and clear decorative anodizing should be avoided.

Can 2036 T4-PB be formed, bent or molded?

Designed for cold stamping in the T4 condition — draw promptly after solution treatment while natural aging is incomplete, allow generous bend radii and expect springback higher than steel.

What is the maximum service temperature of 2036 T4-PB?

2036 T4-PB 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.

What is the difference between 2036-T4 and 2036-T6?

T4 is the default condition — the standard supply condition for automotive body sheet: best combination of press formability and as-formed strength. T6: rarely supplied; used only where maximum strength of a formed 2036 part is needed after shaping. Yield strength is 195 MPa in T4 versus 310 MPa in T6.
