DuPont Cable Material Comparison: Why Are Most DuPont Cables on the Market Substandard?
In electronic engineering and DIY projects, DuPont cables are widely used for connections. However, after conducting market research and laboratory tests, we discovered that most DuPont cables available for sale today do not use high-quality copper as their conductive material. Instead, they are made of iron and aluminum, which significantly reduces conductivity and introduces safety hazards.
This raises a crucial question: Why do manufacturers continue producing and selling substandard DuPont cables despite knowing they are not up to standard? This article will analyze the differences in DuPont cable materials and introduce how Meelaefe is solving this problem by producing high-quality, pure copper DuPont cables.
1. Conductive Material Analysis: Iron & Aluminum vs. Pure Copper
Through rigorous material testing, we found that most DuPont cables on the market use iron and aluminum instead of high-quality copper. Below is a detailed comparison of these materials:
| Material | Resistivity (Ω·mm²/m) | Conductivity (Relative to Copper) | Safety Concerns |
|---|---|---|---|
| Pure Copper (99.999% Oxygen-Free Copper) | 0.0172 Ω·mm²/m | 100% (Best Conductivity) | High safety, long lifespan |
| Aluminum | 0.0282 Ω·mm²/m | ~65% | Oxidizes easily, poor contact, brittle |
| Iron | 0.096 Ω·mm²/m | ~18% | High resistance, rusts easily, poor conductivity |
From this comparison, it is clear that iron and aluminum perform far worse than copper in conductivity. Aluminum’s conductivity is only about 65% of copper, while iron is as low as 18%.
Using these substandard materials leads to unstable current transmission, causing excessive heat generation, poor contact, and even cable breakage under high loads, creating serious safety risks.
2. Market Confusion: How Price Pressure Leads to Inferior DuPont Cables
Meelaefe DuPont cable features oxygen-free copper conductors, ensuring high conductivity, low resistance, and enhanced durability compared to standard market alternatives.
Currently, a 40P DuPont cable is sold for around $4.89 on platforms like Amazon and AliExpress. After deducting production costs, platform fees, and shipping expenses, manufacturers would suffer a loss if they used pure copper for production.
This forces manufacturers to cut costs by using iron and aluminum instead of copper, disregarding safety standards. As a result, electronic engineers and hobbyists unknowingly purchase low-quality cables that are unsafe for use.
This irresponsible market behavior has flooded the industry with inferior DuPont cables, misleading consumers while compromising safety and performance.
3. Meelaefe DuPont Cables: 99.999% Pure Copper for Superior Performance
To counteract this issue, Meelaefe has committed to producing high-quality DuPont cables by using 99.999% oxygen-free copper as the conductor. We also utilize UL-certified UL1007#22AWG wire, ensuring that every cable meets the highest electrical standards.
Meelaefe DuPont Cable vs. Substandard Market Alternatives
| Comparison | Meelaefe DuPont Cable | Common DuPont Cables (Iron/Aluminum) |

| Conductor Material | 99.999% Oxygen-Free Copper | Iron, Aluminum |
| Resistivity | 0.0172 Ω·mm²/m (Low) | 0.0282-0.096 Ω·mm²/m (High) |
| Current Carrying Capacity | Up to 3A | Only 0.5A |
| Durability | No oxidation, long-lasting | Easily oxidizes, fragile |
| Safety | Stable, no overheating | High risk of short circuits and fire |
