1235 Aluminum Sheet Supplier: पन्नी, Thin Coil and Buyer’s Guide
1235 Aluminum Sheet Supplier: पन्नी, Thin Coil and Buyer’s Guide
परिचय
Buyers searching for a 1235 aluminum sheet supplier are usually sourcing thin, high-purity aluminum in coil for converters—cable shielding, adhesive tape, बैटरी पन्नी, bottle caps and flexible packaging.
One point should be clear up front: in commercial production 1235 is supplied almost entirely as aluminum foil and thin-gauge coil, roughly 0.006–0.2 mm thick, rather than as thick flat sheet.
As a rolling mill and supplier, we provide 1235-O/H18 foil and thin-gauge coil slit to width, with the certificates and export service converters need, and we also supply the true flat sheet grades (1050/1060/1100) when a thicker plate is required.
This guide clarifies the product, विशेष विवरण, अनुप्रयोग, supplier capabilities and how to order.
What Is Aluminum 1235?
1235 is a commercially pure 1xxx-series aluminum with a minimum 99.35% aluminum content, strengthened by cold work and softened by annealing.
It is valued for ductility, जंग प्रतिरोध, good surface quality and economy, which makes it a standard converter foil. Its controlled chemistry (typical ASTM limits) है:
| तत्व | अल | और + फ़े | घन | एम.एन. | Zn | का |
| 1235 | ≥99.35 | ≤0.65 | ≤0.05 | ≤0.05 | ≤0.10 | ≤0.06 |
Purity matters for every converter process that follows.
A clean, low-impurity foil rolls to a thin gauge with fewer pinholes, coats and laminates more evenly, and keeps the bright surface that tape and packaging products rely on; coarse iron or silicon particles would show as defects after coating or as weak points when the foil is flexed.
1235 thus sits in a deliberate position—purer and more ductile than manganese-bearing 3xxx converter alloys, yet produced in the high volumes and gauges that make it more economical than the very highest-purity capacitor or electronic foils.
Foil vs Sheet – What 1235 Actually Is
Aluminum products are classed by thickness, and this determines whether 1235 is the right alloy at all:
| रूप | विशिष्ट मोटाई | Common alloys |
| पन्नी | नीचे के बारे में 0.2 मिमी (रोल) | 1235, 8011, 1060, 1070, 8079 |
| पतली चादर | about 0.2–6 mm | 1050, 1060, 1100, 3003 |
| तश्तरी | above about 6 मिमी | 1060, 3003, 5052, 5083, 6061 |
So a “1235 sheet” is, व्यवहार में, 1235 foil or thin-gauge coil near the 0.2 mm upper limit. If you genuinely need flat sheet above 0.2 मिमी, ए 1050/1060/1100 sheet is the correct product; specifying 1235 there would be unnecessary and may not be available as plate.
मानक विशिष्टताएँ
| पैरामीटर | Range for 1235 पन्नी / thin coil |
| मनोवृत्ति | हे (कोमल, अत्यन्त साधारण), एच18; also H22/H24/H26 |
| मोटाई | about 0.006–0.2 mm (some gauges to 0.3 मिमी) |
| चौड़ाई | लगभग 100-1600 मिमी, slit to the converter width |
| मुख्य | 76 मिमी (3 में) या 152 मिमी (6 में) ID |
| सतह | अकेला- or double-bright, dry and oil-free |
| आपूर्ति | jumbo roll or slit narrow rolls; length to order |
The temper should be chosen from what happens to the foil next. Most converters start with soft O foil because it conforms, laminates and wraps without spring-back and survives embossing and forming;
harder H18 web is used where the finished strip or gasket must stay rigid and resist deformation, and intermediate H2x tempers trade a little softness for added strength. Matching the temper to the downstream step, rather than ordering one hardness for every job, prevents cracked or wrinkled foil on the converting line.
विशिष्ट अनुप्रयोग
-
- Cable-shielding foil and laminated AL/PET tape for wires and electronics.
- Adhesive aluminum foil tape (coated by tape converters) for HVAC and sealing.
- Battery foil and battery-related thin strip, plus capacitor foil in fine gauges.
- Bottle cap and closure stock, cigarette and label foil, and flexible packaging layers.
Each application sets slightly different requirements. Cable and shielding foil is often laminated to PET and must be pinhole-tight at very thin gauges to preserve shielding; tape foil needs a clean, dry surface so adhesive bonds reliably;
battery and capacitor foil demand tight gauge and a clean surface for coating or etching; and cap or label stock needs low earing and a consistent face for printing.
Calling out these needs by end use lets the supplier select the right gauge and temper rather than treating all 1235 foil as identical.
What a Capable Supplier Provides
- In-house foil rolling and slitting to hold gauge, surface and width across lots.
- Jumbo or narrow slit rolls matched to the converter’s line, with consistent re-supply.
- Custom thickness, चौड़ाई, गुस्सा, core and packaging, including private-label options.
- Capacity for multi-ton and container orders as well as trial quantities.
A good supplier also helps you avoid specifying the wrong product. If the application actually needs a flat sheet above 0.2 मिमी, a stronger manganese or magnesium alloy, or a finer capacitor-grade web, the mill should say so and supply the matching grade rather than simply confirming 1235 for every request.
That guidance is part of the value of buying from the producer, not an added cost.
गुणवत्ता, Compliance and Export
Quality control covers thickness across the width, width and length tolerance, सतही गुणवत्ता (no pinholes beyond the agreed limit, no oil or roll marks), and tensile/elongation by temper, with chemistry recorded on the mill test certificate against a heat number.
आईएसओ 9001 mills support SGS/BV inspection; food-contact and packaging gauges can be supplied with the relevant FDA, EU or GB compliance documents.
Rolls are moisture-proof packed on pallets or in cases and shipped FOB/CFR/CIF, commonly with 30% deposit and the balance against the bill of lading.
How to Verify the Supplier and Order
- Confirm the supplier rolls and slits in-house via a video of the line and the gauges produced.
- Request production-gauge samples and run them on your coating, laminating or slitting equipment.
- Match the MTC and compliance documents to the sample and target lot.
- Approve a signed sample, then order with thickness, चौड़ाई, गुस्सा, मुख्य, quantity and destination.
This verification matters because foil is consumed in very large areas: a small drift in gauge, surface or temper quickly becomes a large amount of defective converted product.
An in-house mill controls the lot from rolling through slitting, so repeat orders match the approved sample and certificates, while a reseller sourcing different spot coils cannot guarantee the same web.
Running production-gauge samples at normal speed and approving a signed standard is therefore the most reliable protection for ongoing orders.
