From rich and powerful people to today’s average middle class person, Gold has been worn as jewelry for many different reasons and in many different styles. Usually when one thinks of gold, they think of the most common color of gold that is yellow.

There several color alloys from pink to blue, but one of the most popular alloys used among gold jewelry today is white gold.

The Wonderful Uses of Alloys 2 years 38 weeks ago

Alloy superconductors are used to make very light, small and strong magnets in bullet trains-The train uses the help of a magnet to move as though it is floating. This reduces the loss of electrical power as a result of friction between the train and the track.

Brass for Jewelry 1 year 6 days ago

Brass has a muted yellow color, which is somewhat similar to gold. It is relatively resistant to tarnishing, and is often used as decoration and for coins. Years ago, polished brass was often used as a mirror. And, Brass is a mixture of copper and zinc. The ratio of zinc and copper can be varied to create a range of brasses with varying properties. By contrast, bronze is principally an alloy of copper and tin. Bronze does not necessarily contain tin, and a variety of alloys of copper, including alloys with arsenic, phosphorus, aluminum, manganese, and silicon, are commonly called bronze.

Gold has a varied history - It used for more than making gold jewelry 1 year 6 weeks ago

Gold is a precious metal. Historically, it has been used for stores of value (bars) for jewelry, electronics, dentistry, and as actual money (coinage). It is a yellow element found in nuggets that can actually be ruby or black when divided.

It is the most malleable metal known. When other elements are it forms alloys. This will increase the hardness and can create exotic colors. Adding copper gives a redder color, iron more blue, platinum white, aluminum creates purple.

Implementing Business Process Management Projects Using a Phased Approach – Analysis Phase 2 years 20 weeks ago

During the Analysis phase of a business process management automation or re-design project, information gathered during the requirements phase is compared, reviewed, prioritized, sequenced, and identified for change. The primary Analysis Phase objective is to determine the probability that specifications addressed in each requirement satisfy stakeholder needs, expectations, and constraints. Functions that work in a target process are sequenced and prioritized, and those that don’t work are identified for change.
