Purity: 0K / Non-Gold. This item is likely brass (copper-zinc alloy). It contains 0% gold content and is a base metal industrial component.

Industrial Brass Electrical Terminal Lug (Non-Gold)

Type

Industrial Electrical Hardware / Grounding Block

Purity

0K / Non-Gold. This item is likely brass (copper-zinc alloy). It contains 0% gold content and is a base metal industrial component.

Gold Type

Yellow Brass Alloy (likely C360 Free-Cutting Brass). The greenish-yellow tone and oxidized patina are characteristic of industrial brass, not gold alloys.

Weight

15g - 25g. Dense base metal weight. Brass has a density of approximately 8.4-8.7 g/cm3, significantly lower than 18K gold (15.5 g/cm3).

Description

This is a dual-screw mechanical terminal lug or grounding block. While its yellow-gold color often confuses laypeople, it is a functional piece of industrial hardware made of brass. Used in electrical distribution to join or terminate wires, it features a rectangular body with two compression screws. It lacks the refractive index, luster, and hallmark requirements of jewelry-grade gold.

Key Features

Functional set screws, rectangular extruded body, horizontal striations from the extrusion process, and mechanical wear patterns.

Color & Finish

Dull greenish-yellow with an oxidized, matte industrial finish. Surface shows heavy mechanical abrasions, tooling marks, and characteristic brass patina rather than gold luster.

Hallmarks & Stamps

No precious metal hallmarks (e.g., 585, 750, 14K) are visible. If stamped, it would likely feature part numbers or wire gauge ratings (e.g., AWG sizes).

Dimensions Estimate

Length: 25mm - 35mm; Width: 10mm - 12mm. Industrial scale for electrical conductivity.

Gemstones & Inlays

None. This is a functional industrial hardware piece with no decorative elements.

Clasp & Closure

Two slotted steel or brass set screws used for securing electrical wiring within the terminal block.

Chain & Links

Not applicable. The main body is a solid extruded rectangular bar with drilled and tapped holes for the screws.

Craftsmanship Details

Mass-produced via extrusion and automated drilling/tapping. Low-precision machining consistent with disposable industrial hardware.

Authentication Indicators

RED FLAGS for gold: Extruded surface lines, presence of steel-style slotted screws, lack of hallmarks, and the specific 'brassy' greenish hue. Brass often appears more 'yellow-green' compared to the 'orange-yellow' of high-karat gold.

Origin & Maker

Commercial electrical hardware manufacturer (e.g., Burndy, Ilsco, or generic industrial supplier). Likely produced in a mass-manufacturing facility.

Era & Period

Modern Industrial / Contemporary. Common hardware design used in electrical panels and grounding systems from the mid-20th century to present.

Age Estimate

Unknown; modern era. Visible oxidation and wear suggest it has been in service within an electrical enclosure for several years.

Cultural Significance

Represents 20th-century industrial standardization in electrical engineering and power distribution.

Condition Notes

Poor/Industrial grade. Significant surface scratches, tool marks from screwdrivers on the screw heads, and dulling of the metal surface due to oxidation.

Value Estimate

Melt/Scrap Brass Value: Approximately $0.05 - $0.15 USD based on current yellow brass scrap prices per pound. It has no value as a gold item.

Care & Maintenance

Does not require precious metal care. If used for its intended purpose, cleaning with a wire brush to ensure electrical contact is standard.

Similar Items

Gold-plated connectors (which would have a much brighter, mirror-like finish) or architectural brass hardware. Distinct from genuine bullion or jewelry.

Interesting Facts

Brass is used in electrical components because it is a good conductor and much cheaper than gold, though high-end connectors are sometimes 'gold-plated' to prevent corrosion. This item is solid brass, not plated.
