How to distinguish inferior phosphorus copper plate

As a kind of alloy material widely used in the current market, phosphorus copper plate is used in many industries. However, in reality, some friends in the first contact with this kind of material, the advantages and disadvantages of it are not very understanding. Here is a look at the specific advantages and disadvantages of the discrimination method.

Industry insiders said that fake and shoddy phosphorous copper plate is easy to surge expansion, expansion is a variety of curves generated on the surface of this material, this kind of problem is the vertical length of all products, the root cause of expansion is because fake and shoddy manufacturers seek high efficiency, pressure is large, resulting in the next cold rolling telescopic, telescopic product sheet metal bending will crack, The hardness of its products is greatly reduced.

At the same time, the counterfeit phosphor copper plate surface often has the surface condition, the surface is due to the rolling groove damage caused by the product surface irregular uneven shortcomings.

In addition, the inferior phosphocopper plate material is not uniform, the residue and the manufacturer's guide equipment is simple, easy to stick steel, this residue after biting hot rolled strip is easy to form scab, these are in fact will cause sheet products prone to scab.

In addition to the above factors, the surface surface of inferior phosphor copper plate raw materials is prone to cracks, the reason is that its tube blank is adobe, soil drilling holes, adobe in the refrigeration link, due to the effect of internal stress, and then will cause cracks, after cold rolling will also have cracks.
