Preparation

Preparing a scrap load for top-of-sheet pricing

Page brief. Target keyword: how to prepare scrap metal. Audience: scrappers and contractors prepping a load before a yard run. Funnel stage: consideration. The page should answer: how do I sort, strip, and stage a load so it grades cleanly at the scale?

The single biggest lever a seller controls is sort quality. A pile that walks in as "mixed non-ferrous" pays the lowest common-denominator price; the same pile, separated into bare bright copper, #2 copper, brass, and aluminum, can pay 30–80% more for the same weight. This category covers the practical prep work: what to sort, what to strip, what tools earn their keep, and how clean is clean enough.

What this category covers

Each topic below corresponds to a step in a typical prep workflow.

Sort by metal type — separating ferrous from non-ferrous and copper from brass from aluminum
Strip insulated wire — when stripping pays, when it doesn't, and what tools speed it up
Remove attachments — fittings, motors, and contamination that drop a load into a lower grade
Stage and weigh — pre-scale tactics so you know what you're walking into

Sort decisions by metal

The matrix below sketches the prep upside vs. effort for the metals most household scrappers see. For grade definitions, see the Scrap Guide → Grades and Copper & Wire.

Metal / form	Sort upside	Effort	Notes
Bare bright copper	High	Low (visual)	Single biggest payout per pound on most yard sheets
#1 vs. #2 copper	High	Medium	#2 has solder, paint, or oxidation; cleaning lifts it to #1
Insulated wire	Medium–High	Medium–High	Stripping converts to bare copper grade; depends on copper recovery %
Brass (yellow vs. red)	Medium	Low	Magnet test won't help — by color and density
Aluminum sheet vs. cast	Medium	Low	Mixing forces the whole load to cast pricing
Stainless 304 vs. 316	Low–Medium	High	Most yards pay one stainless rate; 316 only matters for larger loads
Prepared steel	Low	Medium	Cutting to under 5 ft × 18 in lifts most yards' "unprepared" discount

A practical pre-yard checklist

Use this as a placeholder rundown — the writer should expand each into 2–4 sentences with photos.

Lay out a tarp or pallet and rough-sort by metal first
Pull all attached steel hardware off non-ferrous parts (screws, brackets)
Strip wire above the break-even diameter; bag the rest as insulated
Drain motors, compressors, and any sealed unit (mercury, oil, refrigerant rules)
Bundle long ferrous to under 5 ft for the prepared-steel rate
Bag fines (turnings, chips) separately so they're not lost on transfer
Take a phone-camera weight estimate and price it before loading

Tools that pay for themselves

For tool-by-tool depth, see the Scrap Guide → Equipment category. Quick highlights:

A wire stripper breaks even in roughly 50 lb of mid-diameter copper wire
A strong magnet is non-negotiable for sorting stainless and pulling steel
A digital crane scale or floor scale removes the largest source of yard disputes
A reciprocating saw earns its keep on appliance and HVAC tear-out

Frequently asked questions

Is it worth stripping insulated wire?

It depends on diameter and grade. Romex-class wire usually pays better stripped; thin doorbell or telecom wire usually doesn't. The Copper & Wire page lays out the break-even math.

Will the yard re-sort what I bring in?

Yes — every yard does its own grading at the scale. A clean sort is for your benefit; a sloppy sort means the grader picks the lowest-paying grade in the pile.

Do I need to remove the motor from an appliance?

For appliances under "white goods" pricing, usually no. For mixed metal recovery, pulling the copper-bearing motor and selling it separately almost always pays.
