BARE MATERIAL

The strips must be clean and free of detrimental defects, which must be specified by agreement between the customer and the supplier when requesting the quote and in the order. Normally, a small residual layer of lubricant is left on cold-rolled products, which is authorised unless otherwise specified.

ROUGHNESS EN 1654

This must be agreed between the customer and the supplier when requesting the quote and confirming the order.

SURFACE CONDITION EN 13599

The strips must be clean and free of detrimental defects, which must be specified by agreement between the customer and the supplier in the request for quotes and in the order. Normally, a small residual layer of lubricant is left on cold-drawn products, and this is acceptable unless otherwise specified. Discolouration is acceptable, provided that it is not detrimental to the use of the product.

ELECTROLYTIC TIN PROCESS TYPES AND TYPES OF TIN COATINGS AND TIN ALLOYS EN 14436

ProcessDescription
Process for matt electrolytic coatings.This is the standard finish of a traditional electrolytic bath.
Process for bright electrolytic coatings.Coatings with a bright appearance are obtained using baths that contain one or more suitable brightening agents (brighteners). Their presence may not be desirable in subsequent melting or soft soldering processes. Furthermore, they may be beneficial for frictional properties (low friction or sliding contacts).
Process for flow-brightened electrolytic coatings.Flow-brightened electrolytic coatings are obtained by heating a matt electrolytic coating above its melting point for a few seconds and then cooling it. The coatings preserve their sheen after cooling. In practice, flow brightening is not used for coatings with thicknesses above 5 μm (slip risk) or for coatings that are already bright.

NOTE – Tin electrolytic coatings may experience a spontaneous growth of metallic filaments (the combined effect of humidity and mechanical stresses, for example). This phenomenon is highly undesirable for electrotechnical applications (risk of short circuit). The risk of this happening can be reduced by flow brightening, using tin-lead alloy coatings or inserting a suitable sublayer.

The appearance depends on the type of liquid film cooling, the type of coating and the technique used to remove excess molten metal. The surface may have a bright or matt appearance, or a combination of both. The appearance of the coating does not affect its suitability. If there are special requirements for the appearance of the coating, these requirements must be agreed at the time of the quote and/or order.

COPPER STRIP: CHARACTERISTICS AND SPECIFICATIONS

SUPPLY AND PACKAGING FOR THE TRANSPORT OF COPPER STRIPS

VINCO specializes in the manufacture of strapping with different qualities, finishes, coatings and cutting ranges from 0.05 mm to 5.0 mm thick and from 3.0 mm to 1,250 mm wide. We have ISO 9001:2015 and ISO 14001:2015 certifications that apply to the commercialization and slitting, rolling, edging and flattening-cross cutting for steel, stainless steel, aluminum and non-ferrous metals such as copper.

Copper strip is available in different alloys, all of which have excellent electrical and thermal conductivity. These copper strips are used in the stamping sector, the automotive sector and for electrocomponent parts, among others.

In terms of technical properties, the density of copper strapping is 8.9 kg/dm³ and VINCO offers several supply and packaging options such as coil or spooled supply:

  • In Rolls with strapping: this type of packaging cordons off the strapping to provide greater stability when transporting the goods. Within this modality, the product can be supplied strapped by arrangement -radial or perimeter-, by material -plastic or metallic-, by coil arrangement (clockwise or counterclockwise), with separation between coils and with cardboard core.

  • The supply of spooled strapping takes advantage of the material giving uniformity to the strap with wooden, metallic, plastic or cardboard core reels. 

  • The Helycoil format strap incorporates cardboard separators that group the product in the form of a roll or cookie.

In addition, the packaging and palletizing in which we can supply strapping comes in different types of pallets: square, round, custom-made or europallet.

All these supply options and types of packaging include protective elements to ensure that the product arrives in perfect condition: box, lid, intermediate cardboard or wooden blocks, corner protectors, dustproof plastic bag, paper and VCI damp-proof plastic, phytosanitary and maritime packaging and damp-proof bags.

To calculate the strip weight based on the coil dimensions in a quick and easy way, we have a tool specially designed for this purpose: the weight calculator.

COATINGS AND TOLERANCES

Bare copper strip (uncoated), electrolytic tin plating (s/EN 14436), hot-dip tin plating (s/EN 13148) can be supplied.

In addition to the coatings defined in International Standards, VINCO can supply strip with the following non-standard coatings: brass plating, copper plating, nickel plating, gold plating, electroplating, silver plating, pre-painted/lacquering, tin plating, selective plating.

Thickness tolerances for copper strips are given in EN 13599 and EN 1652 and are applicable for general and electrical uses with thicknesses from 0.05 mm up to and including 25 mm and widths from 10 mm up to and including 1250 mm. However, in the case of coated material, thickness tolerances are governed by EN 14436 and EN 13148, which involve the thickness of the strip before tinning and the thickness of the tinned strip.
