Why can 1235 aluminum foil replace 1145 aluminum foil?
The 1xxx series of pure aluminum, which has an aluminum content of over 99.3% and incredibly low impurity levels, includes the chemically very comparable numbers 1235 and 1145. They have almost the same chemical makeup.
Similar performance and processing
The ductility, conductivity, and corrosion resistance of the two alloys vary just a little. In the majority of production procedures and final applications, they can be used interchangeably without materially altering the functionality of the final product.
1235 aluminum foil is more affordable and readily available.
In the present market, 1235 foil has more vendors and a larger production capacity. On the other hand, 1145 is becoming less popular due to lower productivity and greater costs. 1235 is a better option when considering supply stability and cost-performance.
Industry-recognized substitute
1235 has supplanted 1145 as the industry standard in flexible packaging, capacitors, cable shielding, and pharmaceutical foil applications, particularly in situations where ultra-high purity is not essential or when cost is a concern.

1235 aluminum foil FAQs
How does the cost of 1235 aluminum foil become determined?
The market price of aluminum ingots, alloy temper, thickness, width, order quantity, and surface treatment are some of the variables that affect the pricing. Competitive prices and tiers of discounts are available for large and recurring orders.
Is it possible to base prices on square meters or weight?
Indeed. Depending on your project's requirements and preferences, we provide customizable price choices based on kilograms (kg), square meters (m2), or per roll.
Is a minimum order quantity (MOQ) in effect?
Small-volume orders are supported by standard standards, although special sizes or finishes could call for a minimum order quantity. To confirm specific product requirements, please get in touch with us.
What kind of packaging does 1235 aluminum foil typically come in?
Usually, rolls are reinforced with export-grade cartons or wooden boxes that have not been fumigated after being packed with plastic film, moisture-proof paper, and EPE foam. Pallets are used to transport heavy goods safely.
Is it possible to personalize the packaging?
Of course. To satisfy branding, e-commerce, and international shipping needs, we provide size-adjusted export boxes, vacuum sealing, anti-static packing, and custom logo printing.
Which certifications and export documentation are offered?
We can facilitate seamless customs clearance worldwide by providing Certificate of Origin (CO), Packing List, Commercial Invoice, Quality Inspection Report, MSDS, and SGS Test Reports.
Which colors are available for 1235 aluminum foil that has been color coated?
Silver gray, champagne gold, matte black, glossy white, high-gloss blue, wood grain, and stone pattern are just a few of the many color options available in chalkco. On request, custom RAL colors (such as RAL9005 black and RAL7035 gray) can also be obtained.
Is it possible to anodize 1235 aluminum foil?
Indeed. For usage in nameplates, applications requiring resistance to corrosion, or decorative finishes, 1235 aluminum foil can be anodized. Its oxide layer is marginally softer than that of alloy-grade foils, nevertheless.
Is heat sealing possible for 1235 aluminum foil?
Indeed. 1235 foil can be used in heat-sealable packaging for food, medicine, and other items by using heat-seal coatings like PE, PP, or PVC.
Is 1235 aluminum foil appropriate for conductive or electrical applications?
Indeed. 1235 aluminum foil is used extensively in electronic applications such as capacitors, battery current collectors, and cable shielding because of its high purity and strong conductivity.
Why choose GNEE as your 1235 aluminum foil supplier?
Free samples
GNEE provides free samples of 1235 aluminum foil so you may assess the applicability and quality of the product more accurately. To evaluate important factors like coating, color, and processing performance, you can ask for samples in particular alloy tempers, thicknesses, or surface treatments. This reduces procurement risk and speeds up decision-making. For samples, get in touch with us.
Reduced prices
Repeat business and large orders qualify for special reductions that provide you a financial edge and increase your competitiveness in the market. We are dedicated to mutual success and long-term collaborations.
Outstanding control over flatness
Andritz leveling rolls on our production lines guarantee that the finished foil has a smooth surface, superior flatness, and enhanced laminating performance and appearance.
