What You Need To Know About Scrap Metal Grades

The economy and the environment benefit both when scrap metal is recycled since recycled scrap is reused over and over again, which means much less scrap is sent to landfills. By participating in aluminium recycling, scrap metal can be recycled indefinitely without losing its integrity, which gives it even more benefits. We’re going to talk about the different grades of scrap metal and how to get the highest price for scrap metal in this post. In this post, we’ll explain the different grades and how to get the best price for scrap metal. Metals like aluminium are usually in high demand at local scrap yards – and they fetch a good price. Collectors (even casual collectors) can earn a good living by collecting high-quality scrap aluminium. Among the best scrap yards in Australia, Botany Scrap metal, is one of the most established.

Mixed Scrap

The lowest price you’ll get is when you have a mix of different metals in varying degrees of cleanliness. Cleaning and sorting mixed scrap will usually increase your cost.


Copper is acceptable to most scrap services in otherwise clean brass if it contains no more than 5% other material.

Stainless Steel

The term “clean stainless steel” refers to stainless steel with less than 5% other materials, and “dirty stainless steel” refers to stainless steel with more than 5% other materials.


There are several grades of aluminium. Aluminium food and drink cans are at the lower end and are expected to be relatively dry and clean. If it contains less than 5% other metals and all insulation, screws, or metal trim is removed, it is considered a clean aluminium sheet, otherwise, it is considered a dirty aluminium sheet. In the case of extruded aluminium that has under 5% of other metals, dirt, insulation, or plastic mixed in, it is considered clean, whereas if it has more than 5% of those materials mixed in or shows signs of significant corrosion, it is considered dirty.

Solid Copper

Two grades of solid copper are available. Copper #1, which cannot contain brass or large amounts of corrosion, includes copper tubing and pipes without fittings if they aren’t corroded. Copper wire that has no insulation and is about 12 gauges thick is considered #1. Copper wire that contains over 5% other metals or is in severe corrosion is considered copper #2. Copper pipe with brass fittings still attached and wire thinner than a pencil leads without insulation fall into this category.

Copper Wire

Depending on the thickness of the insulation and the weight of the copper inside, insulated copper wire has three grades. Copper wire 25% includes heavily insulated wire and is the lowest grade of copper. Even though copper wire 45% has thinner insulation, it is still thinner than a pencil lead on the inside. Copper wire 55% has thinner insulation and is typically around 12 gauge or smaller in thickness.

It is crucial for scrap metal collectors to understand metal grades in order to assess scrap metal’s potential value at the scrapyard, since why not focus on scrap metal that fetches the highest price? As well, collectors need to know where to find specific scrap metals in large quantities. There are three types of metals – ferrous, non-ferrous, and alloys. Each of these categories represents its properties and usually impacts its value. When it comes to scrap metal and aluminium recycling, it’s essential to understand the value of each grade prior to collecting scraps. Here at Botany Scrap Metal, we’re happy to answer any questions.

Ferrous Metals:

It is common to find ferrous metals at large construction sites, home renovations, and automobile repair shops, but ferrous metals are all prone to corrosion and oxidation (rust). Though some ferrous metals have additional elements to enhance their properties, they are generally prone to corrosion and oxidation. Unlike other metals, ferrous metals like iron and nickel have significant magnetic properties, which are useful for collectors. It comes without saying that these metals are heavy.

Non-ferrous Metals:

There is no iron in non-ferrous metals. Aluminium, copper, silver, and gold are some examples of non-ferrous metals that are often in high demand at the scrap yard. These are magnetic and corrosion-resistant metals. Clean, pure scrap can fetch the best price, as aluminium can be found in old screen doors, home siding, playground equipment, and even end-of-life appliances. Scrap aluminium is always in demand. 

Metal Alloys:

The metal alloys are created by melting separate metals, mixing them together, and allowing them to solidify. They are most commonly fabricated by melting separate metals, mixing them together, and allowing them to solidify. The most efficient way to recycle alloys is to recycle only common materials. Alloys are used in industry because they have enhanced properties – like hardness, strength, and machinability. It is usually the only way to reuse alloy metal meaningfully.
