[New Product] Lead-Free Free-Cutting Phosphor Bronze KFX41 (C5099)

[New Product] Lead-Free Free-Cutting Phosphor Bronze KFX41 (C5099)

Lead-free bronze round bars are in stock in various sizes from domestic materials (Fujii Manufacturing Co., Ltd.)!

The newly developed "lead-free free-cutting phosphor bronze" maintains the mechanical properties and machinability of free-cutting phosphor bronze while incorporating elements that have no environmental impact, achieving a fully RoHS-compliant free-cutting phosphor bronze. Traditionally, a small amount of lead was added to copper alloys to enhance machinability, but since lead is a harmful substance to the human body, its use has been restricted by regulations such as the recent RoHS directive. It has been registered in JIS as of 2025 (C5099). We appreciate your consideration of this lead-free free-cutting phosphor bronze as an alternative in light of future environmental regulations. 【Features】 ■ Achieves a fully RoHS-compliant free-cutting phosphor bronze by adding elements that have no environmental impact while maintaining the mechanical properties and machinability of free-cutting phosphor bronze. *For more details, please download the PDF or feel free to contact us.

We accept age-hardening treatment of beryllium copper (C1720).

We accept age-hardening treatment of beryllium copper (C1720).

To fully realize the true value of beryllium copper, aging heat treatment is necessary. The products purchased from us will undergo heat treatment.

Beryllium copper is an alloy that adds a small amount of beryllium to copper. It has the highest strength among copper alloys, possesses high springiness, and features non-magnetic properties, spark-free operation, and high corrosion resistance. Furthermore, it has properties suitable for metal processing, molding, and machining, and is widely used in mechanical parts, electrical and electronic component contacts and switches, electrodes requiring strength and conductivity, heat-resistant wires, brushes, sockets, and probe pins. Beryllium copper undergoes precipitation hardening, where beryllium precipitates within the structure, resulting in tensile strength and hardness values that are among the highest for copper alloys (up to 1500 N/mm² for C1720). This process is known as aging treatment (heat treatment); however, after aging treatment, there can be cases where bending processing leads to cracking or where machining resistance is high, making it difficult to process effectively. Since its machinability is not as good compared to brass, it is often the case that the material is partially processed before heat treatment for finishing, or that aging treatment is performed after machining. There are recommended settings for heat treatment that are somewhat fixed. Our company collaborates with businesses that have heat treatment furnaces to provide aging treatment for materials purchased from us, such as those from NGK (Nippon Gas Co., Ltd.).
