- In twisted-in-wire brushes, the filament material is twisted between two wires. This type of brush is primarily used to clean the internal walls of pipes.
- Like all other Brush India brushes there is a wide range of possible filament types. The middle of the brush consists of what is called the ‘soul’, which is usually made of two twisted wires. The thickness of the twisted wires can vary. It determines the strength as well as the fill density of the brush.
Types of Spiral:
- Single Spiral Your choice of fill bristles are twisted between two (2) stem wires
- Single Spiral - Double Stem Your choice of fill bristles are twisted between four (4) stem wires
- Double Spiral – Double Stem Two (2) layers of your choice of fill bristles are twisted between four (4) stem wires.
Types of Material:
- Carbon Steel
- Stainless Steel
- Synthetic Fibers
- Animal Fibers
- Vegetable Fibers
- Non-Ferrous Wire: Aluminum, copper, phosphor bronze brass, nickel, silver.
- Brass Wire: Rust-proof and spark resistant, brass provides gentle brushing action.
- Phosphor Bronze Wire: Similar to brass with better shape retention
- Carbon Steel Wire: Typically used in applications where abrasion is required in dry environments. High carbon is utilized for deep cutting where aggressive abrasion is required.
- Stainless Steel Wire: Rust-proof and strong and ideal for applications that involve stainless steel or aluminum. Will not leave ferrous deposits.
- Oil Tempered Wire (Flat Wire): Flat wire is the most aggressive brushing material available.
- Crimped or Straight: A crimped, or wavy, bristle extends the life of the brush and is ideal for abrasive cleaning. Straight bristles are softer and more flexible
