It is typically made of high-quality steel wire that is carefully selected based on specific diameter and tensile strength requirements. The steel core ensures the wire maintains its shape and can withstand the tension applied during cutting operations.

2. Diamond Beads:

Diamond beads are the key cutting elements of the diamond wire. These small cylindrical or spherical segments are embedded onto the steel core at regular intervals. Each diamond bead contains synthetic diamonds, which are created through advanced processes to possess the desired hardness and durability. These synthetic diamonds are carefully selected for their quality and uniformity.

The diamond beads are available in various sizes and configurations, depending on the intended application. They are precisely positioned and attached to the steel core using methods such as laser welding or electroplating. The bonding material, typically a metal alloy like bronze or nickel, securely holds the diamond beads in place.

3. Bonding Material:

The bonding material plays a critical role in ensuring the diamond beads remain firmly attached to the steel core throughout the cutting process. It provides a secure bond while allowing the diamond beads to rotate freely and maintain their cutting efficiency.

The bonding material is usually a metal alloy that is compatible with both the steel core and the diamond beads. Bronze and nickel are commonly used due to their excellent adhesion properties and resistance to wear and corrosion. The bonding material is carefully selected to provide a balance between strength and flexibility, ensuring the diamond beads remain securely in place while allowing them to move smoothly during cutting.

The combination of the steel core, diamond beads, and bonding material forms a cohesive unit that makes up the diamond wire. The high strength of the steel core provides stability and structural integrity, while the diamond beads, with their exceptional hardness, enable efficient cutting of the concrete. The bonding material securely holds the diamond beads onto the steel core, ensuring they remain in place throughout the cutting process.

This well-engineered composition of diamond wire allows for precise, fast, and efficient cutting of various types of concrete, making it a valuable tool in construction, demolition, and infrastructure development projects.
