FLUXES FOR AL ALLOYS IN TABLET FORM

HA UK's products in tablet or briquette form are designed to be plunged below the metal surface. In this form, accurate control of addition weights is achieved, and for some metallurgical applications such as hydrogen removal or grain refinement, introduction of the flux sub-surface is necessary to promote an efficient treatment.

HYDROGEN REMOVAL

GASEX N3/100

Hexachloroethane free nitrogen releasing degassing agent for application with aluminium and its alloys with the exception of alloys where the presence of sodium is detrimental.

ECOGAS 16

Hexachloroethane free degassing tablet giving extremely low levels of fume in operation, with exceptionally fast breakdown and minimum melt turbulence. A grey coloured tablet or block. It is used to degas most aluminium alloys with the exception of alloys where the presence of sodium is detrimental. ECOGAS 16 is virtually fumeless in operation, thus avoiding the environmental problems associated with hexachloroethane based degassers.

HYDROGEN ADDITION

GASINAL 108/100

Gassing agent application with aluminium permanent-mould casting gives a controlled introduction of gas into molten aluminium in order to eliminate cracking and schrinkage defects, and also to improve the surface finish of diecastings. Non-hazardous classification for supply!

GRAIN REFINEMENT

SILIFIN 165

Grain refining agent for application with aluminium alloys. Hexachloroethane free grain refining tablet based on salts of titanium and boron. Used for aluminium alloys except conductive alloys. Producing a paste like dross which can be thickened slightly with COVERLUX 0021 for easy removal of the dross. Low levels of fume in operation.

SILIFIN VM 1655

Grain refining agent for application with aluminium alloys with an increasing boron content.

GRAIN REFINER 3

Hexachloroethane free grain refining tablet based on salts of titanium and boron. Used for most aluminium alloys except conductive alloys.

MODIFYING FLUXES

VERALUX SH 10/200

Sodium modification tablet of exothermic nature for application with hypo-eutectic aluminium-silicon alloys. Provides an extended modification effect (typically 40 minutes) due to its high yield. The exothermic reaction time is approximately 2 minutes.

VERALUX 041/500

Long-term sodium modification tablet for application with hypo-eutectic and eutectic aluminium-silicon alloys containing up to 12% silicon. This product is applied to the metal surface and helps to maintain a constant sodium level after initial modification. Best suited to use in gravity diecast applications.
