The design and material from which they are made make it possible to process various surfaces : metal, wood, concrete, marble, granite and others. The article discusses in detail the features of brushes, the main working material of which is metal.
The main purpose of metal brushes
This tool is primarily intended to perform the following tasks:
- Cleaning welding areas from dirt.
- Removing burrs from the end of the workpiece.
- Removing scale from a metal surface.
- Removing traces of corrosion from metal surfaces.
- Removing dried dirt from a metal surface.
- Removing plaque from a metal surface.
In addition, this tool is very often used to remove seams from a metal surface that remain after welding.
After the welding seams are completely removed, the place on the metal surface where they were located must be treated with a special anti-corrosion compound.
Functions of wire brushes: for cleaning metal surfaces, for removing rust and paint
Metal brushes are used to solve many problems and are actively used in repair and construction work. Using cord brushes you can:
- grinding the surfaces of products made of different materials, but mainly metal;
- roughing and finishing;
- removal of various contaminants: stains, dirt, paint, varnish, rust, scale, slag;
- cleaning surfaces before welding;
- polishing welding joints;
- removal of burrs;
- treatment of hard-to-reach places.

Characteristics of a metal brush
This type of tool is manufactured in strict accordance with GOST requirements. Documents for metal brushes must include information regarding the size of this type of tool, the material of the pile, as well as the number of rows.

Brushes made of bristles or bristles: horse, boar.
Natural bristle brushes are used to clean high fluoride powders.
Direct purpose - finishing skis after applying lubricant, used to remove soft paraffin and to treat surfaces after applying powders and accelerators to them, neutralizing electrostatics from the sliding surface. Main brush for powders. Polishing bristles remove static electricity from the ski surface. The number of passes is unlimited - until the ski starts to shine.
A wild boar bristle brush has stiffer bristles than horsehair. It can be used for finishing after cold paraffins, as well as powders, especially hard ones. Considered a second brush for applying powders.
Types of metal brushes
Depending on the area of application, it is customary to distinguish the following types of metal brushes:
- Special attachments that are intended for various types of electric tools. For example, for a drill.

- Brushes for cleaning metal surfaces with metal bristles.
- Brushes designed for cleaning metal surfaces with nylon bristles. This type of tool is used to work with materials such as plastic or wood.
- Brushes designed for cleaning metal surfaces, with brass bristles.
Nylon brushes are most often used to apply various types of patterns to a wooden surface. After which the wooden surface is varnished or painted.
- As for the rows of bristles of such brushes, their number can range from one to six.
- Based on the material from which the handle is made, metal brushes are divided into plastic and also wooden.
- The main distinctive features of plastic handles for metal include a high level of strength, as well as durability.

Nylon brushes
Nylon brushes are needed for working with paraffin, namely cleaning the structure of the ski after applying paraffin. If you do not carry out the ski cleaning procedure or do it poorly, then the ski will roll extremely poorly for the first couple of kilometers, until it is independently cleared of snow on the track. Brushes come in different hardnesses: hard - for cold (frosty) paraffins, medium - for warm ones.
There are also soft brushes - they are used for final polishing of skis after applying powders and accelerators.

Metal brushes made of bronze, copper, brass and steel
Bronze or copper brushes are used to clean the sliding surface before applying waxes or powders. When using a fluoride remover, bronze brushes are also used.
Copper brushes
After applying the first base layer of paraffin, its remains are removed with a scraper, and then comes the turn of the copper bristles. With its help, paraffin residues are removed from the sliding surface. 5-6 passes are recommended in order to remove the substance as much as possible. It is important that some of the paraffin remains for the adhesion of subsequent ointments or powders, so soft metal (copper) is the optimal solution here.
Brass brushes
If a gliding ointment is used, brass bristles are used before applying it. 1-2 passes from toe to heel are recommended to create conditions for the ointment to adhere to the previous layer of paraffin. Brass is a harder metal than copper, so fewer passes are needed. Otherwise, there is a chance to destroy the paraffin layer.
Steel brushes
Steel brushes are intended for the professional, and are not necessary for the average hobbyist. They have a very fine steel fiber that removes paraffin from the smallest structure. Only used when applying hardeners in severe frost or powders in all temperature ranges.
