Supplier — AvekGlob Company — offers copper foil at a reasonable price from the manufacturer in a wide range of cross-sectional dimensions. The supplier guarantees the timely delivery of products to any address specified by the consumer.
Copper foil, having a high conductivity of electricity and heat, is universal, but is most often used as an electrical conductor for printed circuit boards, solar panels, consumer products, etc. The copper foil is obtained by cold rolling technologies. Before finishing, the products are annealed. There are copper foil with bound oxygen in the composition and without it.
Urgency of application
Numerous applications of copper foil include roofing, building and enclosing structures, shielding, circuit boards and heat exchangers. These copper coils can be supplied on fibrous, aluminum, steel and plastic cores with an internal diameter of up to 20 «.

Physical and mechanical properties
Depending on the type of heat treatment, the characteristics of copper foil are as follows:
- For soft (annealed) copper — the limit of time resistance, MPa — 190… 200, elongation — 35… 40%;
- For semi-solid copper — the limit of temporary resistance, MPa — 230… 250, relative elongation — 15… 20%;
- For hard copper — the limit of the temporary resistance, MPa — 260… 270, the elongation — 8… 10%.
Copper foil is supplied in rolls of copper sheet in thicknesses from 0.0005 «to 0.010». Delivery can be performed on plastic or aluminum cores. Types of copper foil finish — uncoated, with tin or zinc coating. Specific electrical resistance of copper foil should not exceed 17.48 * 10 -9 Ohm-m (0.01748 Ohm * mm 2 / m).
Supplier — AvekGlob company — offers to purchase copper foil in a wide range of thickness and width. Products can be bought at a price formed on the basis of European and world standards of production. Implementation is possible in bulk and retail, for regular customers, a flexible system of discounts operates.
