How Much is 1 KG of Pure Copper Worth?

If you’re in Australia, particularly in a city like Sydney,  1 kg of copper today is worth something like AUD $10–$13.50/kg (if it’s “scrap copper”) and what you get depends a lot on how clean/pure the copper is. 

Below is a long-form, blog-style discussion of what “1 kg of copper” really means in Australia, why the value varies, and how to think about selling it if you have some sitting around.

What “1 kg of copper” usually means in Australia

In Australia, if you bring copper to a scrap metal yard, wiring, pipes, off-cuts, the price is determined by its condition, purity and cleanliness, not just raw “metal value.”

• “Bare-bright” or “clean” copper (stripped, unalloyed, uncoated, minimal contamination) tends to fetch the highest price, around AUD $10.00 to about $11.75 per kg. 
• Many scrap-yards quote a slightly broader “good-copper” band of AUD $9.50 to $13.50/kg depending on the yard and local demand. 
• If the copper is less pristine, mixed with solder, paint, other metals, oxidised, or insulated wiring, the payout can drop to AUD $7.00 – $9.00/kg (or sometimes even lower for coated/insulated wire).  

So realistically: if you have 1 kg of “clean scrap copper,” expect maybe $10–$13/kg; if it’s mixed or contaminated, maybe $7–$9/kg.

Why there’s a range (purity & condition matter)

The variation in price comes down to a few main factors:

• Purity & contamination: Clean, bare copper (no solder, no insulation/plastic, no paint, no fittings) commands a premium. Once there’s solder, corrosion, coatings, or mixed metals, scrap yards discount heavily because they need to spend time and resources to clean/reprocess. 
• Type of copper scrap: “Bare bright” wire, unalloyed pipe, or “mill-berry” copper tends to be most valuable. Pipes, tubing, old fittings, mixed scrap (with solder/paint) often fetch less. 
• Local demand & scrap-yard competition: Prices vary between cities, and even between yards in the same city, depending on supply and demand dynamics. 
• Volume & convenience: Larger quantities tend to get better pricing, because processing and transportation costs get spread out. A few kilos may not fetch as much per kg as larger loads.

What about “pure copper” vs “scrap copper” vs “commodity-grade copper”?

There’s an important distinction between different “types” of copper you might have or buy/sell:

• Scrap copper, what typical people bring to scrap yards: wiring, pipe off-cuts, leftover plumbing/cabling. The prices above mostly refer to this category. 
• Industrial/commodity copper, refined copper metal, traded on global commodity markets (per-tonne basis, large volumes). The “spot price” for copper fluctuates globally and is expressed in USD per pound/tonne. For instance, some commodity-price trackers quote copper at a certain USD per lb or per tonne. 
• Because small-scale recycling in Australia rarely deals in “pure commodity copper,” the prices recyclers pay tend to reflect scrap-metal realities, contamination, processing costs, variability, rather than wholesale metal-market values. 

In other words: if you somehow had 1 kg of highly refined, industrial-grade copper, its “value” could be tied to global commodity prices. But for typical scrap copper from homes, renovations, wiring, plumbing, you should realistically expect the scrap rates above.

What this means if you’re selling copper in Australia

If you’ve got copper lying around (wire, off-cuts, old pipework, scrap from renovation), here are tips to get the best return:

• Strip insulation, remove fittings, solder, paint, deliver “clean, bare” copper. That boosts you from the low-end scrap price toward the higher end. 
• Separate by grade, keep “clean copper wire/pipe” separate from mixed or contaminated copper. Scrap yards pay more for the clean stuff. 
• Collect enough to make volume worthwhile, a few hundred grams may not fetch much; a few kilograms or more typically makes it worth the trip. 
• Shop around, different scrap yards in Sydney (or whichever city you’re in) may have different price bands depending on demand and supply. 
• Stay aware of global copper market trends, big swings in global copper demand/supply sometimes impact scrap rates indirectly (although scrap-yard prices tend to lag or be more localized).

Why copper-prices (scrap & commodity) move, and what to watch

Copper scrap prices, whether global commodity or local scrap, fluctuate due to several factors:

• Global supply & demand: Large-scale demand (construction, infrastructure, electronics, renewable energy) influences wholesale prices. Disruptions (mining issues, geopolitical supply problems) can cause spikes. 
• Local supply & demand, recycling flows: If many people are scrapping copper (e.g. after renovations, building demolitions), the supply at scrap yards increases, which can depress local prices. Conversely, if demand from recyclers is strong (e.g. for resale or export), rates might be better. 
• Copper condition and quality variation: More contaminated or mixed copper, soldered, painted, insulated, tends to result in lower prices because of the processing effort. That’s largely why you see a spread (e.g. $7–$13.50/kg). 
• Currency, transport & local market costs: Scrap-yards factor in costs of handling, refining, transport, local regulation, which influence what they’re willing to pay per kg.

Bottom Line: What 1 kg of Copper is “Worth” in Australia

• For clean, stripped, bare-bright copper scrap: expect around AUD $10 to $13.50 per kg 
• For mixed, painted, soldered, or otherwise contaminated/insulated scrap: maybe AUD $7 to $9 per kg, sometimes less if heavily contaminated or insulated 
• If you managed to sell “refined/commodity-grade copper” (rarely possible to private sellers), theoretically the price may be tied to global metal markets but most everyday copper ends up in scrap-metal markets.
