Aluminium and zinc casting alloys

Aluminium and zinc, and what separates them where it matters.

Designers specify by alloy designation, not by metal. “Aluminium” is not a specification; EN AC-46000 is. The alloy decides what the part will take, whether it can be heat treated, how thin a wall will fill and how the surface behaves under paint or anodising.

Material data

Alloys and material data

Six entries cover practically everything we cast: three aluminium alloys and two zinc alloys, with one aluminium alloy listed both as cast and heat treated, because the difference is large enough to be two different materials in practice.

Aluminium 4

Designation	Common name	Density [g/cm³]	Tensile strength [MPa]	Yield strength [MPa]	Elongation [%]	Hardness [HB]	Typical use
EN AC-46000	AlSi9Cu3	2.75	240	140	1	80	The most common European die casting alloy. Brackets, housings and fittings in general industry, where strength and cost matter more than corrosion resistance and appearance.
EN AC-44300	AlSi12	2.65	240	130	1	60	Parts with thin walls and complex geometry, and parts living in damp or marine environments. The best-flowing of the three.
EN AC-42100	AlSi7Mg0,3	2.68	170	90	2.5	55	Gravity cast parts that will be heat treated. This row shows the condition before heat treatment — see the next row for T6.
EN AC-42100 T6	AlSi7Mg0,3 T6	2.68	290	210	4	90	Load-bearing brackets and structural parts where strength and fatigue properties are critical. This is the combination behind the heat treated bracket in our portfolio.

Zinc 2

Designation	Common name	Density [g/cm³]	Tensile strength [MPa]	Yield strength [MPa]	Elongation [%]	Hardness [HB]	Typical use
ZP0410	Zamak 5	6.6	330	230	7	91	The stronger of the two common zinc alloys. Brackets and fittings that carry load, and parts that will be tapped.
ZP0400	Zamak 3	6.6	280	200	10	82	The standard zinc die casting alloy. Housings, covers and visible parts where dimensional stability and surface matter most.

Aluminium data: EN 1706. Zinc data: typical published values for the as-cast condition (ASTM B86 / EN 12844). None of the figures are measured on parts cast here. The “Run here” column reads “To be confirmed” until we have confirmed which alloys are actually in production.

Reading guide

How to read the table

Tensile strength (Rm) is the stress at which the part breaks. Yield (Rp0.2) is the stress at which it starts to deform permanently — and that is usually what you design against, not Rm.
Elongation (A) tells you how tough the alloy is. Low elongation means brittle: the part breaks without bending first. Zinc has substantially higher elongation than die cast aluminium.
Density decides the weight of the part. The same geometry weighs 2.4 times more in zinc than in aluminium — and since we price on metal weight, that feeds straight into the part price.
The values apply to standard test bars. A real part with varying wall thickness and some porosity normally sits lower. If you have a critical strength calculation, say so — then samples have to be taken from a real part, not read off a table.

Which of these alloys we run day to day is being confirmed. If you have a requirement on the drawing, state the designation in your enquiry — and we will tell you whether we run it, whether we can bring it in, or whether we would propose something else.

We cast in aluminium and zinc. The feedstock arrives as ingot from regular suppliers, and the aluminium is secondary aluminium, meaning remelted metal from car parts, beverage cans and facade products. It is supplied by Metallco at Toten in Norway, where aluminium scrap is re-alloyed into full casting alloys to international standards.

The alloy is chosen together with you. If you have a requirement on the drawing, we follow it. If you only have a functional requirement — “it must take 4 kN and live outdoors” — we propose an alloy as part of the review.

Which specific designations we run day to day is not published yet. On the alloy table you will find the most relevant standard alloys with material data from the alloy standards, clearly marked as to what is a standard value and what is confirmed here.
