PACKAGING: Protective packaging to prevent surface scratching and oxidation during storage and transit. Each roll is individually wrapped with anti-tarnish interleaving. Custom packaging available for bulk orders.

IMPORTANT NOTICE: Precision brass strip is susceptible to surface oxidation and contamination. Store in a clean, dry environment away from moisture and corrosive chemicals. Handle with clean gloves to prevent contamination from skin oils. For ultra-thin grades (0.01-0.02mm), exercise additional care during handling to prevent wrinkling, creasing, or tearing. When cutting, use appropriate sharp tools or scissors for clean edges — deburring may be required for precision applications. For hard temper grades, note that formability is reduced compared to soft temper — pre-annealing may be beneficial for complex bending operations. Always verify thickness with a micrometer before critical shimming applications. Multiple layers can be stacked to achieve custom gap heights.

Constraints

Atomfair Rolled Brass Foil requires precision annealing to achieve its range of hardness states. The foil's mechanical properties are directly dependent on the annealing process parameters.

Annealing Process Dependency: Hardness states (Soft, Quarter-hard, Half-hard, Hard) are achieved through precision annealing of the copper-zinc alloy.

FAQ

How does the hardness state of Atomfair Rolled Brass Foil affect its formability versus tensile strength for stamped heat sink fins?

Softer states (O) offer elongation ≥25% for deep drawing, while hard (H) states maximize tensile strength to 450–510 N/mm² for rigidity. The trade-off is clear: soft (O) gives 80–120 HV for forming, hard (H) delivers 135–185 HV at only ≥5% elongation. This allows engineers to select the optimal temper for either stamping complexity or load-bearing performance.

Is Atomfair Rolled Brass Foil compliant with international dimensional and material standards for integration into global automotive heat sink supply chains?

Yes, it complies with ASTM B36/B36M-01 and JIS H3100:2000, ensuring direct acceptance in US and Japanese manufacturing specifications. Dimensional tolerances are ±0.003 mm on thickness (0.01–0.15 mm) and ±0.1 mm on width (4–600 mm), matching precision requirements for high-volume heat sink assembly. This eliminates requalification costs in existing supply chains.

What storage or handling precautions are needed when using Atomfair Rolled Brass Foil in its quarter-hard (1/4H) state for decorative applications?

No special dry-gas storage is required for short term, but the copper‑zinc alloy’s golden surface can tarnish in humid environments over weeks. For 1/4H material (105–145 HV, elongation ≥15%), standard anti‑tarnish interleaving and climate‑controlled storage (below 60% RH) are sufficient to maintain the aesthetic finish. The foil’s excellent processability allows direct cutting and bending without pre‑treatment, but handling with clean gloves prevents fingerprint etching.

Assessment

Atomfair High Precision Rolled Brass Foil offers excellent processability with uniform surface quality and adjustable hardness via annealing, making it suitable for heat sinks, decoration, and structural components. However, its thin gauge requires careful handling, and high hardness states exhibit reduced formability.

Positive

Uniform surface quality and consistency: Smooth surface, flat plate profile, and exceptional batch consistency ensure stable performance in mass production, reducing variability in downstream processes.
Excellent formability and processability: Easily cut, bent, and formed; compatible with various secondary processing technologies, lowering production costs and improving processing efficiency.

Trade-offs

Thin foil requires precision handling: With thickness down to 0.01 mm and tolerance ±0.003 mm, the foil is susceptible to deformation or damage during handling and requires careful manipulation and storage infrastructure.
Limited ductility at high hardness: The Hard (H) temper offers only ≥5% elongation, significantly restricting deep forming or bending operations compared to softer tempers.
