(i.e. nitrogen or argon) or an atmosphere containing maximum 5-10% hydrogen in nitrogen. Don’ts • Do not touch, move or manipulate Argentium silver while it is at red heat, as this may cause cracking. • Be careful not to overheat. -
Page 4: Forming And Decorative Techniques
Argentium 960-Pure has greater ductility than traditional sterling silver - this means that the metal can be worked longer and further between each annealing, thus decreasing manufacturing time and labour. -
Page 5: Heat-Hardening Treatments
Heat-hardening treatments Argentium silver can be formed into complex shapes in its fully soft condition and by means of heat treatments have its hardness and durability increased. Method 1 - air-cooling Step 1 After annealing or soldering allow Argentium silver to air-cool to room temperature. -

- wait until the red glow has completely disappeared. Flux Argentium 960-Pure is highly resistant to firestain, it is therefore only necessary to flux the seam to be soldered rather than applying flux to the whole piece. The following fluxes are recommended (use as directed by the manufacturer): •... -
Page 7: Welding
Welding applications offer efficient production methods, using localised heat for joining materials. Welding technologies provide excellent alternatives to the use of solders. The weldability of Argentium Original opens new avenues for the design and production of silverware and jewellery items. -
Page 8: Investment Casting
Investment casting Argentium 960-Pure Argentium 960-Pure is suitable for smaller scale casting. For high volume casting, please use ‘Argentium Professional Casting’ alloys. Flask burn-out • Allow the flask to stand for 2 hours before the burn-out cycle. • Do not overload the burn-out furnace - this ensures that the centre of all the flasks will reach the required temperature for complete burn-out and that there is sufficient air-flow to remove moisture from the cured investment powder. -

Argentium silver its tarnish resistance. Certain practices used in the trade with traditional sterling silver may harm Argentium’s protective germanium oxide and care must be taken not to contaminate the surface of Argentium silver with other metals/materials during polishing processes. -
Page 10: Manual Polishing
Manual polishing Important information It is important to use separate polishing wheels, mops and compounds for Argentium silver to avoid contaminating the surface with residues from other metals or materials - surface contamination can diminish the tarnish resistance of Argentium items. If this is absolutely not possible, then polishing wheels and mops must be thoroughly cleaned/raked before use. - Page 11 Surface passivation - chemical treatment As an alternative to the heat passivation process it is possible to chemically treat Argentium silver, which allows the protective germanium oxide layer to develop naturally over a period of time underneath the protective layer.

Page 12: Long Term Care
Long term care Argentium silver is low maintenance, easy to care for and simple to keep clean. Simply wipe away any dust or finger marks with a soft cloth or, for more intricate pieces, wash them in warm soapy water, rinse and dry immediately to avoid water marks. - Page 13 For sales and technical enquiries please email info@argentiumsilver.com or visit our website argentiumsilver.com ARGENTIUM are registered trademarks of Argentium International Limited. ® ®...
