Black Matfol
The black or armature wires used for armature are produced by heating at 800 to 900 degrees. The size of this wire is from 1.5 to 6 mm and it is packed in 15 to 20 kg coils. The applications of black wire include packaging, molding, agriculture, reinforcement and making galvanized wire.
Galvanized Fattol
Galvanized wire is produced in two hot and cold states:
🔴 Cold state: As it was said in the above section, these wires are made of wire They are produced black. In this production method, black wire is drawn with an electrolaser device and a layer is created. This layer is thinner than the layer used in the hot method. During this process, the wire becomes flexible and resistant to rust. >
🔴 hot state: In the hot state, the wires are produced through the hot rolling process, in this state, they heat the black wire to reduce its carbon, this increases the flexibility of the wire, then with They cover the molten metal and prepare it for various works, including making all kinds of laces.
💠 Fattol spring or carbon
Spring wire is one of the steels that have a lot of carbon, if the carbon in the steel is high, it is known as high carbon steel. The industrial industries of furniture making, agriculture, machining, etc. have many applications.
Mashar
In this wire, copper alloy is used, and that is why it is named as such, and it is used in the form of coils or spools in household industries, electrical industries and other industries.
