TECHNICAL SPECIFICATION
A full description of test methods and detailed test results are available
on request.
Alloys: The alloys used for Crystal cored solder wires conform to the
purity requirements of the common national and international standards.
A wide range of wire diameters is available manufactured to close
dimensional tolerances.
Flux: Multicore Crystal solid fluxes are based on modified rosins and
carefully selected activators. In use they exhibit a mild rosin odour and
leave a small quantity of clear residue.

Cored wire: Multicore Crystal cored solder wires are designed to give
fast and sustained wetting on both copper and brass. This can be
demonstrated using spreading tests on both substrates under standard
conditions for the Multicore products and comparable competitor
products. After 5 seconds, area of spread is measured to form a
comparative index indicating total flux efficacy.
Multicore Crystal flux cored solder wires out-perform competitor
products, which require a higher flux content and leave more residues
whilst achieving poorer spread.

HEALTH AND SAFETY
WARNING: The following information is for guidance only and users
must refer to the Material Safety Data Sheets relevant to specific
Multicore Crystal flux cored solder wires before use.
Health Hazards and Precautions: Inhalation of the flux fumes given
off during soldering should be avoided. The fumes are irritating to the
throat and respiratory system. Prolonged or repeated exposure to rosin
or modified rosin based flux fumes may lead to the development of
respiratory sensitisation and occupational asthma.
Multicore Crystal solder wires must always be used with suitable fume
extraction equipment to remove fumes from the breathing zone of
operators and the general work environment.
Solder alloys containing lead give off negligible fume at normal soldering
temperatures up to 500°C.
Normal handling of lead alloy wires will not cause lead to be absorbed
through the skin. The most likely route of entry is through ingestion but
this will not be significant if a good standard of personal hygiene is
maintained. Eating, drinking and smoking should not be permitted in the
working area. Hands should be washed with soap and warm water after
handling solder wire.
Waste disposal: Wherever possible, waste solder wire should be
recycled for recovery of metal. Otherwise it should be disposed of
according to local or national regulations.
