Cable aluminum foil roll utilizes the airtightness and shielding properties of aluminum foil. After one or both sides are coated with plastic film, the aluminum-plastic composite foil is formed to wrap the cable for shielding and protection. The cable aluminium foil is usually made of 1235-O aluminum foil, the aluminum content of which is not less than 99.35%, and the effect is very good when used as a cable aluminum foil.
The overall requirements of the cable aluminum foil roll are not high, and the requirements for the length of a single pair are very demanding. The cable aluminum foil requires less oil on the surface, no holes, and high mechanical properties, because the surface quality of the aluminum foil is the main factor affecting the peel strength, and the main surface quality problems are oil spots, corrosion, and overoxidation. In terms of length, the length of the cable aluminium foil is only allowed to be longer, not shorter. This requires careful calculations when casting and rolling billets. Cast-rolling billets should be kept as long as 10 or 12 times the customer's required length, plus an additional 3% error. In terms of mechanical properties, that is strength, the communication cable industry does not set a high standard for cable aluminum foil, but most customers require the strength of the cable aluminium foil to be greater than 70MPa or 80MPa.
The price of 1235-O aluminum foil for cable is a problem that many people care about. Generally speaking, the quotation model of the aluminum processing industry is basically the same. The price of cable aluminum foil roll is composed of the market aluminum ingot price plus the processing fee, which affects The price factors also include the nature of the manufacturer and product specifications.
1. Aluminum ingot price: As the price of aluminum ingot fluctuates daily, the quotation will fluctuate.
2. Manufacturer strength: A strong manufacturer, the raw materials used are of good quality, the production input cost is high, the price is relatively high, and the order quality is reliable.
3. Different specifications: different user needs are different, the thickness and width of the selected products are different, and there are certain differences in product prices.
