The sharp run-up of gold prices at that time motivated the development of
substitute materials. In conditions under which most other metals either tarnish
or corrode away, gold remains inert and extremely durable. In the world of
computing and communications, speed is more important than cost, so the use of
gold has become a standard. Some motivation for this comes from concerns that
less inert metals might have an adverse effect on long-term health. Gold has a
very low shear strength, and a thin film of gold between critical moving parts
serves as a lubricant - the gold molecules slip past one another under the
forces of friction and that provides a lubricant action. Silver is actually the
best conductor, followed by gold.

Electronic products are one of the bigger users of gold. By using All Waste
Matters as your precious metal refiner, you may be able to turn these seemingly
insignificant scraps into profit. Gold is a bio-compatible metal, meaning it can
be placed in contact with a person&China

health.
Every time we go to visit our clients on a precious metal refining job, they
are stunned that this pile of what they considered to be scrap waste is worth
any money - often, their eyes light up once we give them a quote.
.
At the moment, more than 80 per cent of e-waste ends up in landfills, making it
a pretty serious environmental issue.
Dentistry
Gold is being used for fillings, crowns, bridges and orthodontic appliances.
The most basic use in glassmaking is that of a pigment.
In addition to this, most of the times, the gold is bound up with a lot of
other hazardous chemicals so it's always a good idea to ask a professional
precious metal refiner for help.
Gold is used in jewellery for its wonderful colour and brilliant lustre, but
it can be found also in many products that we use in our everyday life. A small
amount of gold, if suspended in the glass when it is annealed, will produce a
rich ruby colour. This thin film reflects much of the very intense solar
radiation of space, protecting the astronaut's eyes and skin.
Gold is also used when making specialty glass for climate-controlled
buildings and cases. This means that in telecommunications, computers,
automotive electronics and defence systems where safety is critical, gold # is
indispensable. The importance of high quality and reliable performance justifies
the high cost.
For electronic applications, the resistance of gold to environmental effects
is perhaps its most important property as it assures that the technical
performance of gold wires or gold electroplating remain essentially unaltered
with time. In the vacuum of space, organic lubricants would volatilize and they
would be broken down by the intense radiation beyond Earth's atmosphere.
However, the amount of gold used in dentistry is starting to rise again. It's
e-waste that can easily end up as a huge burden on the environment if each unit
is not discarded properly.
It is important for manufacturers to be aware of procedures in their
processes which may generate precious metal scrap suitable for recycling. Copper
is cheaper than precious metals, but it's also much slower in transporting
electrons.
When thinking about conductors, most people picture copper, probably because
it's the metal that is commonly used. According to the American Environmental
Protection Agency, "Experts estimate that recycling 1 million cell phones can
recover about 24 kg (50 lb) of gold, 250 kg (550 lb) of silver, 9 kg (20 lb) of
palladium, and more than 9,000 kg (20,000lb) of copper. Silver, however,
tarnishes quickly when in contact with air.
The beneficial material properties of gold include outstanding resistance to
corrosion, the ease with which it can be worked and high thermal and electrical
conductivity.
Of all the minerals, gold is probably the more useful thanks to its diversity
of special properties.
As experts in precious metal refining All Waste Matters can take care of the
whole process, offering a completely free no obligation sampling and assaying
service and advising you on your manufacturing procedures which could be
producing valuable scrap precious metal.
In general, the more sophisticated the equipment and the greater the need for
reliability, the greater is the requirement to exploit the advantages of gold as
a material.
Gold's many qualities make it the metal of choice for a wide variety of
industries.
Edge connectors used to mount microprocessor and memory chips onto the
motherboard and the plug-and-socket connectors used to attach cables all contain
gold.
Gold is also used as a lubricant between mechanical parts.
Aerospace
Many parts of every space vehicle are fitted with gold-coated polyester film.
Gold conducts electricity very well, it does not tarnish, it melts at low
temperatures making it very easy to work, it can be drawn into wire, it can be
hammered into thin sheets and it alloys with many other metals. Without this
coating, dark coloured parts of the spacecraft would absorb significant amounts
of heat. A small amount of gold dispersed within the glass or coated onto the
glass surface will reflect solar radiation outward, helping the buildings stay
cool in the summer, and reflect internal heat inward, helping them stay warm in
winter.
Electronic parts
Electronic components made with gold are highly reliable."
Many businesses don't realise that they can be leveraging scrap gold to their
advantage, and all they need is a specialist precious metal refiner to take care
of # this on their behalf, and ensure that they are getting the best possible
price for their precious materials.
The key is to remember that with the mass proliferation of electronic devices
also comes the massive build-up of electronic waste.
The key ingredient to maximizing the obvious potential of electronic waste is
proper recycling and extraction.
The visor on the helmet of an astronaut's space suit is coated with a very
thin film of gold.
In phones, most of the gold is in the SIM card, the main board and the
smaller components on the back of the LCD screen. Gold is used in connectors,
switch and relay contacts, soldered joints, connecting wires and connection
strips. It was much more generously used in dentistry up until the late 1970s.
Glassmaking
Gold has many uses in the production of glass. There's a lot of obsolete
electronics out there with TVs, computers, phones having lives of 5 years or
less. This film reflects infrared radiation and helps stabilize the temperature
of the spacecraft. The gold in these components is generally electroplated onto
other metals and alloyed with small amounts of nickel or cobalt to increase
durability. Laptops, phones, cameras and many other devices use gold to connect
components
