Material characteristic index

  1. The cross-sectional area ratio of the copper layer is 15%-30% (the cross-sectional area ratio of the copper layer of the standard product is set to 20%, and special products with any cross-sectional area ratio can be produced according to customer requirements);
  2. The mass ratio of the copper layer is 30 %-60% (The weight ratio of the copper layer of the standard product is 45%);
  3. Coating uniformity: the thinnest point of the copper layer> 90% of the average thickness of the copper layer;
  4. The deviation of the straightness of the finished product: ≤0.15% ;
    5, finished tolerance: width & plusmn; 0.3mm, thickness plusmn &; 0.05mm;
    . 6, copper-aluminum bonding strength (shear strength) is greater than the shear strength of pure aluminum (usually ~ 80Mpa is 50MP);
    . 7, Finished product shape: both sides of the section are full rounded corners, R=1/2 thickness;
  5. Finished product toughness (Temper): soft or hard delivery;
  6. Finished product bending: after bending the wide side by 90° ( For the design of the bending radius, please refer to “Enterprise Product Standard”), there should be no cracks in the copper layer, and no separation between the copper layer and the aluminum core;
  7. The surface of the finished product: After grinding and polishing, there should be no visible defects;
  8. The finished product Delivery state: coated with antioxidant (anti-oxidation life> 180 days under normal temperature and normal state), coated with plastic insulating film.
