1. Platinum. The high priestess of precious metals. Heavier than lead and higher in value than gold. It takes 8 tons of mined ore to produce just 1 ounce of the pure metal. it is virtually impervious to oxide attack. not easily worked.
Silver 925. Pure silver and its compounds have many uses. it has been found to be a powerful antibiotic when ingested. It has a distinctive whiteness about it when polished, though this is short-lived as it tarnishes and dulls if left unmaintained.
18 ct white gold. Often used to substitute platinum. this alloy of gold contains 75% gold with the remaining percentage shared with silver and palladium. easy to work but with a greyish colour a preference to see this metal rhodium plated is common.
9ct white gold. Contains over 60% silver giving it a whitish lustre. commonly used as a higher value alternative to silver. works with relative ease.
Palladium. Used widely in the medical electronic and jewellery industry. incredibly palladium left undisturbed at room temperature will absorb 900 times it’s own volume of hydrogen.
9. chrome. Chromium is what gives ruby’s their red colour. Can be alloyed with mild steel to make stainless steel. It’s salts when dissolved in solution, can be used to chrome plate many different metals. one of the brightest most durable finishes.
Zirconium. A metal of high corrosion resistance used in surgical instruments when alloyed with other metals. It is a common element found on the surface of the moon and other uses include artificial limb manufacture
Mild steel. The most common metal used in industry. Easily worked, though not excessively so, it will almost always require surface treating as it’s pure form readily oxidises within minutes. Electroplates very well.
10. nickel. Used as a base for chrome in the chrome plating process and has been used to compound alloys in coins for centuries, in recent years it’s use with jewellery alloys has been restricted as it can cause skin reactions.
Tantalum. Used in the electronics industry for capacitor and resistor manufacture. its a compound element for alloy fortification and causes no immune response when inside the body. With this in mind it can be used for the production of dental alloys.
Titanium. A much revered alloy for high end design and engineering applications. highly resistant to oxide attack and has extreme heat resistance. 35% lighter than steel and almost as strong as the toughest steel alloys. Not without a price! one of the most difficult metals to work.
Stainless steel. A common alloy with many different grades formulated for a huge range of industrial applications from body piercings to engineering appliances for some of the world's most extreme environments.
Niobium. A metal with exception al heat resistance it’s alloyed with other elements in stainless steels and also in alloys with a variety of nonferrous metals, such as zirconium. The metal is used in superalloys for jet engines and heat resistant equipment
Aluminium. The most abundant metal on the planet. 10 times lighter than platinum and approximately 1/30,000 the value! exceptionally light and lends itself well to most manufacturing processes. problems when surface treating.
White metal. An alloy of exceptionally low melting point. specific grades will melt in hot water ! Can be used to cast small intricate objects such as toy soldiers or door handles.
Tin. A soft silver metal with a yellowish hue. Alloyed with many metals notably lead to produce solder. When a bar of tin is bent, the so-called tin cry can be heard as a result of sliding tin crystals reforming.

Finishes shown are stable and durable. The verdigris blue however needs to be used on applications where it will be mostly untouched as this will diminish the blue oxide coating. Lacquers can be applied to further protect these oxide/patinated finishes.
