Overview
585 gold, or 14-karat gold, is a gold alloy containing 58.5% pure gold, with the remainder typically composed of copper, silver, or zinc. This alloy strikes a balance between purity and durability, making it a preferred choice for jewelry and industrial uses. The term '585' refers to the millesimal fineness, indicating 585 parts per thousand of pure gold. Unlike 24-karat gold, which is too soft for many applications, 585 gold offers enhanced strength and resistance to wear. Its versatility allows for a range of colors, including yellow, rose, and white gold, depending on the alloying metals used.
Physical and Chemical Properties
585 gold exhibits a density of approximately 13.0-14.0 g/cm³ and a melting point between 800-900°C, depending on the specific alloy composition. Its notable properties include malleability, corrosion resistance, and the ability to be polished to a high luster. The alloy's hardness makes it suitable for intricate jewelry designs and everyday wear. The color of 585 gold varies based on the alloying metals. For example, copper produces a rose hue, while nickel or palladium creates white gold. These variations allow for diverse aesthetic and functional applications in different industries.
Main Applications
585 gold is widely used in jewelry, including rings, necklaces, and earrings, due to its durability and aesthetic appeal. Its lower cost compared to higher-karat gold makes it accessible to a broader market. Beyond jewelry, it is employed in dental alloys for crowns and bridges, where strength and biocompatibility are essential. In electronics, 585 gold is used in connectors and plating due to its excellent conductivity and resistance to tarnishing. Its decorative applications extend to watches, pens, and luxury items, where a balance of beauty and functionality is required.
Safety and Storage
585 gold is generally safe for use in jewelry and other consumer products. However, some individuals may experience allergic reactions to nickel or other alloying metals, particularly in white gold. Manufacturers often address this by using hypoallergenic alternatives like palladium. Proper storage involves keeping 585 gold items in a dry, cool environment, away from harsh chemicals or abrasive materials. Regular cleaning with mild soap and water helps maintain its luster and longevity.
B2B Procurement Guide
When procuring 585 gold for B2B purposes, verify the purity and alloy composition through assay certificates or supplier documentation. Consider the intended application—such as jewelry, dental, or industrial use—to select the appropriate alloy mix. Pricing fluctuates with gold market trends, so monitor spot prices for cost-effective purchasing. Establish relationships with reputable suppliers who adhere to ethical sourcing practices, such as conflict-free gold standards. Bulk purchases may qualify for discounts, but ensure proper storage and handling to prevent damage or loss.
