DELVA-LOT: Copper Rod & Powder Flux

DELVA-LOT Copper Rod

DELVA-LOT Rod is manufactured in Europe from high purity copper (92.7%) and Phosphorus (7.3%) according to DIN 8513 thus being the most popular amongst installers.

Production involves a special process and high density (8.1g / cm³), in order to foam less than the common welds, making the installer's work easier and more efficient.

Its application temperature is about + 720 ° C and its tensile strength is at 250N / mm².

Available in a set case - 1kg package in 3.2x1.27x500mm rods.

Suitable for high pressure and superheated steam systems, cooling units, natural gas, industry and shipbuilding.

DELVA-LOT Powder Flux

When using copper welding and generally hard welding to join copper with bronze or brass, it is necessary to clean the surfaces with a strong desiccant material. Usually a natural mineral, commonly known as sodium borate or (borax) is used in the form of white powder.

DELVA-LOT Borax, is available in containers of 100gr. The range of application temperatures is from 450˚C to + 800˚C according to DIN EN 1045 FH10. To use with CuP, CuP Ag, Ag welding alloys.


Various Solder Products

Kraft Flux Paste

Deoxidizing, water soluble, in the form of a viscous liquid applied with a brush. Absolutely harmless, simplifies the work, helps to clean the copper and achieve excellent welding. Effective yet non-corrosive.

Absolutely harmless, simplifies any welding work, and cleans effectively the surfaces.

Acts in two phases:

a) In the first phase of oxidation, some of the components are activated at a temperature of + 110°C and destroyed at a temperature of + 180°C (charring). As a result, corrosive components are eliminated and their residues are easily removed.

b) During second phase, the welding phase, the special components are activated at a temperature of + 180°C and due to their high strength, they reach a temperature of + 350°C, a fact that guarantees easy and fast welding.

Kraft Flux Paste is by DIN 8511-F-SW22.

Suitable for forming copper systems and all tin solders.

NOVASIL Silicone

The general purpose NOVASIL silicone is an anti-mold, high quality silicone suitable for sealing joints in non-leachy materials, showing excellent durability.

Available in transparent, white and black.
