K65 Copper Tube Fittings for High-Pressure Applications

K65 Tube for CO2 Applications

formation — Wed, 28 Aug 2019 09:26:56 +0000

Lawton K65 is a high copper alloy with high mechanical strength.

Typical Applications

Tubes for air conditioning and refrigeration, heating and solar engineering, brake line tubing

Temper (DIN EN12449)

R300** soft annealed R420** hard

According to DIN EN 12449

Chemical Composition		Mechanical properties (annealed)
Fe	2.10-2.60 %	Rn	min.>300 N/mm2
Zn	0.05-0.20%	Rn	max.>250 N/mm2
P	0.015-0.15 %	A	min. >25%
Pb	max. 0.03 %
Cu	balance

**Conformity to PED 97/23/EC can be certified through product inspection by a technical inspection agency such as TUV.

Fabrication properties
Cold working	excellent
Electroplating	excellent
Hot-dip tinning	excellent
Machinability	poor

Joining
Brazing	excellent
Soft soldering	excellent
Inert gas shielded
arc welding	excellent
Resistance
welding	good
Laser welding	good

Corrosion resistance

Lawton K65 is insensitive to stress corrosion cracking. Lawton K65 exhibits good resistance in natural atmosphere (also marine atmosphere) and industrial atmosphere. It has a better resistance to erosion and pitting corrosion than Cu-DHP in different types of water and neutral saline solutions.
