Gold and silver, two noble metals with distinct properties, have been combined for centuries to form a versatile alloy known as electrum. This alloy inherits the shimmering luster of gold and the malleability of silver, making it ideal for intricate jewelry and historical coinage. The addition of silver to gold reduces its hardness and melting point, while enhancing its strength and durability. Electrum’s composition varies depending on the ratio of gold to silver, resulting in a spectrum of hues from pale to deep yellow.
What Are Gold Alloys?
What Are Gold Alloys?
Gold, the epitome of luxury and allure, has found its way into our lives for centuries. But what we often overlook is that the “gold” we covet is rarely pure. Instead, it’s an alloy, a harmonious blend of gold with other metals.
Karatage, a fascinating concept, serves as a metric for measuring gold’s purity. Pure gold reigns supreme at 24 karats, but for practical reasons, it’s often too soft to stand alone. Just like a shy introverted, pure gold needs a little help to shine.
So, jewelers have devised a brilliant solution: alloys. These are essentially mixtures of gold with other metals like copper, silver, or palladium, tailored to enhance gold’s durability, color, and versatility.
