CuDLP also known as CuB2
CuDLP or CuB2 is a copper alloy with excellent mechanical properties and good electrical and thermal conductivity. It has good solderability. CuDLP is a low-alloyed copper (Cu 99.9%, P 0.005-0.012%) for the manufacture of machined parts. Cu DLP is used in the aerospace and mechanical industries.
The production of this phosphor makes it oxygen-free and therefore insensitive to reducing atmospheres. Highly ductile and malleable, it is particularly suitable for stamping and boilermaking work. It also has good electrical (90% IACS) and thermal conductivity. It is non-magnetic and non-sparking which makes it a material of choice for parts in explosive environments (explosion-proof tools, crane rollers, etc.).
Field of application of CuDLP
CUDLP copper is used for electrical applications (strips for cables, busbars = interconnection bar, leadframe...), industrial applications (welded tubes, apparatus construction, heat exchangers, radiators...).
