Slow wire brass wires can have different tensile strengths to suit different equipment and applications. This is achieved by a series of wire drawing (quenching) and heat treatment (annealing) processes. Ordinary slow wire brass wire tensile strength between 490-900N/mm2.

The advantages and disadvantages of slow wire brass wire

The good quality of the slow wire brass wire mainly shows the linearity of the wire, the processing stability, the cutting speed, the degree of copper powder and the characteristics of the wire.

The slow wire brass wire has the following characteristics:

Versatility: a wide range of wire types to meet the needs of all types of machine tools

Verticality: suitable for automatic threading requirements

Stability: Processing stability has been tested on various models of machine tools

Cutting speed: Compared with similar products, processing speed shows obvious advantages

Main disadvantages of slow wire brass wire:

(1) Processing speed cannot be improved: Since the proportion of zinc in brass is constant, the energy conversion efficiency cannot be further improved during discharge; taking 0.25mm brass wire to cut 30-60mm thick steel as an example, many domestic users have a cutting speed of 120mm2. /minute or so.

(2) Poor surface quality: copper powder on the surface of the brass wire and copper particles on the surface of the wire due to gasification of the surface of the wire will accumulate on the surface of the workpiece to form surface area copper. At the same time, due to the poor rinsing property, a thicker metamorphic layer is formed on the surface of the workpiece, which will affect the surface hardness and roughness of the workpiece;

(3) The processing accuracy is not high: especially when processing thick workpieces, due to poor rinsing properties, large straightness errors (upper and lower end dimensional errors and drum differences) may occur. Kunshan slow wire
