As the active component of Corrosive-Flux-Paste, AL-Flux 0726 contains a mixture of LiCl, NaCl, KCl, inorganic- and complex- fluorides. Organic carrier systems are used to prepare a wide range of pastes for the flame brazing of aluminium materials. Al-Flux 0726 Flux Paste is typically applied by dispensing and brushing for flame brazing. No component mixing is required. Products are supplied as ready to use products, requiring stirring only.

A low-melting-point flux for brazing aluminium. Flux for joining aluminium to aluminium by flame and induction brazing For joining aluminium to copper/ brass by flame and induction brazing Suitable for flame brazing of aluminium alloys (incl. higher magnesium containing alloys - e.g., AA6063) with Zn/Al filler alloys

A standard flux for brazing aluminium. Brazing agent as combined brazing and fluxing agent for brazing of aluminium

The NOCOLOK® 028 flux paste range contains NOCOLOK® Flux with an organic carrier or water carrier system. Some of these products are cesium complex enhanced. The NOCOLOK® 028 flux paste range is typically applied to braze critical joints by dispense, brush or, in some cases, by spray application. Used in joint situations where filler metal is resent in the form of a clad layer or filler metal shim and wire pre-forms are positioned in the joint area. No component mixing is required. Products are supplied as ready to use products, requiring stirring only.

NOCOLOK® Flux 7028-9028 metallized flux pastes range is a mixture of NOCOLOK® Flux, aluminium filler metal, AlSi 7/10/12, with an organic carrier system. It is widely used where additional filler metal is required and can replace most braze operations where filer metal rings and flux pastes are used. The advantage is that a single product is used; no mixing is required. Products are supplied as ready to use products, requiring stirring only.

During brazing, potassium fluoroaluminates (flux) are generated by the brazing agent in contact with aluminium surfaces. In addition silicon is generated and aluminium/silicon filler metal is formed.

NOCOLOK® Cs Flux is a flux for brazing magnesium aluminium alloys. Brazing agent flux for brazing aluminium specifically for brazing magnesium-containing aluminium alloys (i.e., AA 6063)

NOCOLOK® flux is non-hygroscopic and only very slightly soluble in water (0.2 % to 0.4 %). The shelf and pot life of the flux is therefore indefinite. The flux does not react with aluminium at room temperature or at brazing temperature and only becomes reactive when molten (at least partially molten). The flux leaves a mainly water insoluble residue which need not be removed. Application Brazing agent - as combined brazing and fluxing agent for brazing of aluminium.

NOCOLOK® Flux Drystatic is used to coat aluminium components with flux by utilizing electrostatic attraction to 'dry' flux the surface ready for brazing. It is used extensively in the automotive industry in specialized Controlled Atmosphere Brazing (CAB) furnaces. Application Brazing agent - as combined brazing and fluxing agent for brazing of aluminium (Electrostatic/Dry powder application)

NOCOLOK® Flux Paste is a flux paste specifically formulated for providing a viscous homogeneous mixture of NOCOLOK® Flux (15 – 50%) in an organic carrier for brazing aluminium cladded interfaces where traditional water based fluxing is not suitable. Typical applications include but not limited to: interior tube seams (B-tubes), snap over joints (clinch tubes), tube-to-header joints, internal turbulators. The paste can be dispensed manually by brush or syringe or with automatic dispensing equipment. The paste can be used in both furnace and flame braze process. CsAIF4 can be added to accommodate materials with Mg of up to approximately 0.5 % in furnace brazing. This refers to the combined Mg-level of both components to be joined.

NOCOLOK® Li Flux shows the same outstanding properties and brazing performance of standard potassium fluoroaluminate flux – with further enhancement of the post braze flux residue characteristics. Application Brazing agent flux for brazing aluminium Reduced solubility of post-braze flux residues Uniform structures of post-braze flux residues

NOCOLOK® Li Flux Drystatic is a flux for aluminium brazing with further reduced residue solubility and improved corrosion characteristics and using electrostatic/dry powder coating. Application Brazing agent flux for brazing aluminium Reduced solubility of post-braze flux residues Uniform structures of post-braze flux residues

Paint-F-Flux is supplied in a liquid format with a suitable viscosity for application by spray technique. It is applied by air spray or rolling. Versions PFF Standard: Basic version – market leader PFF C35M: With Cs enhancement for brazing of Al materials with higher Mg content PFF Inner Braze: Newly developed PFF with modified binder – for brazing of close surfaces, particularly for plate fin design of WCAC, for large Oil coolers, for CAC turbulators No component mixing is required. Products are supplied as ready to use products, required stirring only.

NOCOLOK® Precoating can be used in mixture with NOCOLOK® Flux or NOCOLOK® Zn Flux and water to improve adhesion of the flux coating. The system can be applied on external and internal surfaces in order to reduce flux fall-off and dust formation on handling of flux coated components. Proper application of the Precoating/water/flux system shows no negative effects regarding the appearance of the post braze aluminium surfaces, compared to the use of pure NOCOLOK® Flux or pure NOCOLOK® Zn Flux (especially no discoloration effects). Suitable application methods: spraying, dipping or brushing Surface temperature: > 10 °C, with subsequent drying step Recommended thickness of the coating: 10 – 30 μm
