Weiß Bronze

White Bronze Mixer  Just like the other ‘mixer solutions’ we sell, Bronze Mixer can be added to our new copper solution to create a beautiful shade of freshly cast bronze. This brand new solution, exclusive to Real Gold, has been introduced as a replacement for nickel plating solution. Nickel is now banned by the EU for use in the cosmetic industry, as it causes nickel allergy in some people. White Bronze is the ideal substitute for nickel plate, where the surface of the metal is likely to come into contact with the skin, such as on costume jewellery or on spectacle frames. The main uses are listed below. A replacement for nickel to stop nickel allergy. Replaces nickel for use as a barrier layer when electroplating gold onto copper or brass. Makes an excellent key layer when plating silver onto pewter, Britannia metal or other high-tin alloys. Is similar in hardness to nickel with the electrical properties of silver but with superior corrosion resistance. White bronze makes an excellent undercoat forblack chrome. As with our other mixer solutions, you have the same flexibility to create the exact shade of bronze you require. At a low mix ratio it plates an attractive gold shade (2N) of bronze, a white, tarnish resistant coating which resembles nickel. The highest ratio is more like bright chrome.     Features Used for When mixed with our Copper Plating Solution to create white bronze, can be used as a replacement for nickel to comply with EU legislation and avoid nickel allergy Plating any items that will be handled or otherwise come into regular contact with the skin, for example jewellery, lighters and musical instruments Non-tarnish and silver-like in appearance Can be used as a low-cost, tarnish resistant alternative to silver plate for example when repairing musical instruments or up-cycling silver plated antiques Effective as a barrier layer Can be used for plating on non-conductive surfaces; makes an excellent barrier layer between copper/brass and gold – ideal for plating on non-conductive surfaces Base coat Plating an excellent undercoat for black chrome and when plating silver onto pewter, Britannia metal or other high-tin alloys.   Mixing ratio; 1 part Copper Plating Solution to 2 parts White Bronze Mixer – leave to stand for 15 minutes before using     Kennzeichnung gem.

Our White Bronze Brush Plating Solution plates an anti microbial layer of white bronze onto a range of different metals. It can be used instead of nickel because it has a similar hardness has a similar colour can be used to plate a barrier layer between gold on to copper and its alloys We recommend you use our platinum range of electrodes with our white bronze plating solution. Please note: This white bronze plating solution solution is air-sensitive so when you’re not using it, keep the lid tightly shut and try to reduce the air space remaining in the bottle. You can do this by adding marbles or glass beads to the bottle or squeezing out the excess air at the top of the bottle. You can also store the solution in a special syringe that’s available on the online shop. We recommend this solution is stored long-term between 2 – 5 °C. Please use this solution within 4 weeks of purchase. If you don’t follow these precautions then the tin component in the white bronze plating solution will degenerate. Our white bronze brush plating solution is a truly multi-functional product. Because of its anti microbial properties, one of its most important applications is to plate a protective, non-toxic nickel coloured layer onto stainless steel door handles and other touch points, reducing the incidence of microbial transmission.

If you’re planning on creating gold plated copper jewellery or any other decorative or functional item made out of copper that will regularly be worn or handled, white bronze plating is an excellent choice for plating that essential barrier layer between the gold plating and the base layer copper. It is essential because without a barrier layer, the gold plate will eventually diffuse into the copper (including it alloys such as brass) which will result in a patchy, unattractive surface. In the past, nickel plating was used as a barrier layer, but nickel is now banned in the manufacture of jewellery in the EU and so white bronze is the effective, non-toxic and inexpensive alternative. Please be aware that copper jewellery that will be in constant, close contact with the skin (such as earrings or rings) isn’t suitable for this process. Although white bronze plating is non-toxic, it won’t prevent the underlying copper eventually reacting with the skin, leaving greenish markings. For this reason we suggest that white bronze barrier layers are best on pendants that are designed to be worn over clothes, brooches or belt buckles etc.  Operating Conditions and Deposit Data Voltage range 3.2 – 3.5 volts (see notes) Temperature 18 – 25 °C (optimum: 22 °C) Electrode Platinum or copper (see notes) Recommended swab Extra Fluffy Swab Typical copper/tin ratio in plate (%wt/wt) 42:58 (see notes and  X-ray analysis below Plating Rate at (3.2 volts, Platinum electrode) Approx. 0.7 micron per minute (spot) Plating Rate at (3.5 volts, Platinum electrode) Approx. 1.5 micron per minute (spot) Hardness (micro Vickers 10g load) 450 – 500 Hv Density of deposit 8.6 – 8.8 g/cm3 Melting point 800 – 850 °C Stress Medium-high stress (see notes) Special storage requirements Long-term storage: between 2 – 5 °C (see notes) Air sensitive(see notes) Shelf life Use within 4 weeks of purchase and store  between 2 – 5 °CImportant: See notes Health and Safety classification Harmful Special considerations Avoid excess air space during storage (see notes) Transport (UN number) None: Not classified as dangerous for transport   Notes: Increasing the voltage increases the plating rate. An increase offrom 3.0 volts to 3.5 volts more than doubles the plating rate. Increasing the voltage causes the copper to tin ratio to increase. If using copper electrodes, use a voltage range of 2.6 – 3.1 volts. Stress can be relieved by heating to 260 °C for 1 hour. Important note: When coming out oflong term storage, allow solution to reach room temperature before use. As the solution ages, the copper content of the plate increases. Just before plating, we recommend that the work piece be warmedby placing it under a tap to approximately 30 °C. Thickness and consistency will vary over the item. Please refer to ourX-ray analysis illustrating these variations. Please note: This is an air-sensitive solution. When not in use,keep the lid tightly shut and take measures to minimise theair space remaining in the bottle. These can include adding marblesor glass beads to the bottle or squeezing out the excess air at thetop of the bottle. You can also store the solution in a special syringethat’s available on the online shop.Failure to observe the above precautions will result in the degenerationof the tin component in the solution.Please click on the ‘Examples’ tab below for suggestions on howto minimise air contamination.
