## Summary description

LUT TWARDY MIEDZIANO-FOSFOR L-CUP6 is a copper-phosphorus hard solder intended for brazing copper and copper alloys. The product is supplied as a single unit (manufacturer code Czę000418, EAN 5906268905673). It provides a metallurgical bond without flux on copper surfaces and is suitable for plumbing, HVAC, refrigeration and electrical connections requiring a durable, conductive joint.

## Long description

LUT TWARDY MIEDZIANO-FOSFOR L-CUP6 is a copper-phosphorus hard solder designed for brazing copper and copper alloys. Supplied as a single unit, the alloy creates a metallurgical bond on clean copper surfaces without the need for additional flux, producing joints with good mechanical strength and electrical conductivity. The product is suitable for use in plumbing, HVAC, refrigeration and electrical connections where a durable, conductive joint is required.
Advantages
The copper-phosphorus composition allows for flux-free brazing on copper substrates, simplifying preparation and reducing the need for cleaning chemicals. Joints formed with this alloy offer high mechanical strength and reliable electrical conductivity. The material wets copper effectively, promoting consistent capillary action and sound metallurgical joining when proper heating and fit-up are maintained.
Suitable for
Plumbing: joining copper pipes and fittings
HVAC systems: brazing refrigerant lines and components
Refrigeration: making pressure-retaining joints in cooling circuits
Electrical connections: conductive joints on copper components
Key specifications
Alloy type: copper-phosphorus hard solder
Typical applications: brazing copper and copper alloys
Flux requirement: generally flux-free on copper surfaces
Joint characteristics: metallurgical bond with good mechanical strength and electrical conductivity
Supply form: single unit
How to use
Prepare mating copper surfaces by removing oxides, oils and other contaminants to ensure proper wetting. Assemble parts with appropriate fit-up and gap control for capillary action. Heat the joint uniformly until the alloy flows and is drawn into the joint; allow the molten filler to wet and form a continuous fillet. Cool the assembly naturally and, where necessary, remove any residual oxides or flux residues from surrounding areas. Follow standard safety practices for high-temperature brazing, including ventilation and personal protective equipment.
Usage recommendations
Use on clean copper and copper-alloy surfaces for best results; avoid using this copper-phosphorus alloy on ferrous metals or active alloys that require flux. Ensure appropriate heating method and temperature control to achieve consistent brazed joints and preserve electrical conductivity and mechanical strength.
