FAQ

Q1: What is the difference between C12200 copper foil and C12200 copper tube?

A: The material is the same (C12200 DHP copper), but the form is different. Foil refers to flat, thin strips (0.025mm to 3mm thickness typically), while tubes are hollow cylindrical forms. Foil is used for electrical components, gaskets, and cladding, while tubes are used for heat exchangers and condensers.

Q2: What thicknesses are available for C12200 foil?

A: Thickness ranges from 0.0254 mm (0.001") up to 25 mm. The most common foil thicknesses are in the 0.05mm to 3mm range. For specific thickness availability, please contact the supplier.

Q3: What are the available tempers for C12200 strips?

A: Available tempers include:

Annealed – Softest, most formable

Half Hard – Moderate strength

Full Hard – Highest strength, minimal formability

Q4: What is the electrical conductivity of C12200 foil?

A: The physical properties table shows 85% IACS at 68°F. This is the correct value for C12200 (DHP copper). Note that other copper grades like C10100/C10200 can achieve 100-101% IACS.

Q5: What are the common applications for C12200 copper foil?

A: Applications include:

Roofs (building construction)

Chillers (heat exchange components)

Defense (projectile rotating bands, torpedo tubes)

Electrical components

Gaskets and shims

Q6: What is the HSN code for C12200 copper foil?

A: The HSN code is 74102100 (Copper foil, not backed, of refined copper).

Q7: What is the hydrogen embrittlement test mentioned in the specifications?

A: ASTM B577 is the standard for Detection of Cuprous Oxide (Hydrogen Embrittlement Susceptibility) in Copper. This test determines if the copper contains oxygen that could cause cracking when exposed to hydrogen in reducing atmospheres. C12200, being deoxidized with phosphorus, has good resistance to hydrogen embrittlement.

Q8: What is the forgeability rating of C12200?

A: The forgeability rating is 65 (on a scale where free cutting brass = 100). This indicates good hot workability.

Q9: What is the machinability rating of C12200?

A: The machinability rating is 20% of free cutting brass. This means C12200 is relatively soft and gummy, requiring sharp tools and proper lubrication for machining operations.

Q10: What is the difference between ASTM B152 and ASTM B75 for C12200?

ASTM B152 – Covers copper sheet, strip, plate, and rolled bar (flat products like foil)

ASTM B75 – Covers seamless copper tube (hollow cylindrical products)

Select based on the form you need – B152 for foil/strip, B75 for tube.

Q11: What is the thermal expansion coefficient of C12200 foil?

A: Values vary with temperature range:

68-212°F: 9.4 × 10⁻⁶/°F

68-392°F: 9.5 × 10⁻⁶/°F

68-572°F: 9.8 × 10⁻⁶/°F
