Brush wire plays the major element of any kind of brushes, and this article is going to discuss the selection of wires to made a good brush.

In CHOOSING A GOOD SCRATCH BRUSH, we conceptly mentioned that the number of wire ends will great impact the brush performance, and now let’s explore related wire properties, which includes:

● Wire Hardness
Toughness, Tensile Strength, and Yeild Strength
Crimped Pattern

The first property, wire hardness, basically determine the target removal rate of the brush. Harden wires transit source forces pushed from handle/stud by direct or indirect mehod with fewer losses, therefore brush gets higher performance from perspective of removal rates.

The toughness, which is decide by both tensile strength and yeild strength. Toughness impacts the lifespan of brush wires. lower toughness will cause the wire broken or unusable in short time.

Crimped pattern will increase the lifespan and touching area during operation of wires(citation). However crimped pattern increase the wire volume, weight, and somehow lower the hardness of wire. Since the wire volume increased, the production cost increase. Furthermore, the number of wire ends and brush performance reduced

Ideally, brush wires are expected to be strong wires: great hardness, toughness, and straighted; but these properties not only limited by wire dimaters but also, similar to steels, toughness and hardness are conflicted.

Nowadays, the solution about wire properties is choosing the wire with correct properties based on real applications, and this is also the major service offer by DTC/Brutex Industries Inc. Please checkout our product page, and feel free to consult/contact us.
