ALPHA® Fluitin 1535 is an activated rosin cored solder wire developed for general hand soldering applications. The unique activator system offers good thermal stability at pre-soldering temperatures ensuring that Fluitin 1535 performs extremely well on parts and surfaces which present poor or difficult soldering conditions.
Fluitin 1535 leaves post-soldering residues that are hard and which can be safely left without the need to remove them. If the removal of residues is required then semi-aqueous or aqueous systems can be used effectively.

Health & Safety
Q - Can l get Alpha Fluitin 1535 in any other solder alloys?
A - Afraid not we only manufacture in 60/40 tin lead alloys.
Q - Can the post soldering residues be left on the solder joint when finished?
A - Generally these flux reidues are benign after soldering. You should however be aware that the flux activation is classified under J Std as being moderate. If you require a product for more critical applications then you should consider Alpha Fluitin AS or Alpha Telecore Plus which is classified as having a low activation level.
Q - How does SWG (Standard Wire Gauge) compare to metric sizes?
A - 26 SWG is equivalent to 0.4 mm Dia.
22 SWG is equivalent to 0.7 mm Dia.
18 SWG is equivalent to 1.2mm Dia.
Q - What is the smallest wire currently avialable exstock?
A - Currently our smallest diameter wire is 0.010" as shown below.
Alpha Telecore Plus is Lead Free SAC305 alloy
Alpha Reliacore 15 is leaded 63/37 alloy
Q - Health and safety have requested that l look at solder wires that are rosin and resin free do such products exist?
A - Alpha produces a solder wire that is called FT2002. This product contains no rosins or resins and is therefore deemed to be Colophony Free.
This solder wire comes in both Leaded 63/37 and Lead Free SAC305 in most common sizes.
Q - Do l have a choice of reel sizes?
A - Traditionally the electroniocs market has always been 500 gm reels. This continues through today, however the finer wire diameters such as 0.4 mm will only have 250gms wound on to a 500 gm reel.
If the wire is manufactured in the USA then this comes on 1LB reels.
Other reel sizes are available but must meet minimum order quantities in production
Q - I have a water cleaning process at the end of my production lines can you supply a water washable solder wire?
A - Alpha Pure Core solder wire is designed to be washed in water and is a market leader in its field. It is available in both Leaded 63/37 and Lead Free SAC305 alloys
Q - What is colophony and can it cause any health issues?
A - Colophony is a generic term for rosin, this is the sap or sticky substance that derives from pine and spruce trees. Its "stickiness" lends itself to being used in a wide range of products. We have traditionally used this product in fluxes due to these specific properties it can however lead to breathing difficulties and skin sensitivity. Always use fume filtration when soldering and change filters regularly.
Q - What is the difference between rosins and resins?
A - The terms are often used interchangeably, but rosin is a naturally occurring substance, and resin is either a modified rosin or completely synthetic material. Rosins are plant based products and are subject to more natural variation than resins, however resins are commonly used in newer flux formulations due to their more consistent performance.
Q - How does IPCJ-STD-004B flux classification work.
A - Flux designation has three components. The first two letters, RO, RE or OR, represent the basic chemical composition: rosin-based, resin-based or organic acid-based. The next component is flux designation, L, M or H, which describes the flux’s activity level as low, medium or high, and the final component, 0 or 1, this indicates if halides are present.
