Magnesium punishes a borrowed formulation faster than any other alloy we work with. The grade has to be built for the alloy — and then the dilution and spray timing have to be set on your machine, because that is where the yield is decided.
| Model | Position | Dilution | Note |
|---|---|---|---|
| ZP-801 | Workhorse | 1:80 – 100 | The grade to trial first on standard magnesium work |
| ZP-801A | Heavy-duty variant | on request | Where the standard grade runs out of film strength |
| ZP-802 / 802A | Extended series | on request | Additional working points in the range |
| ZP-106 / 106A | Extended series | on request | Additional working points in the range |
Dilution marked on request is confirmed per application by the factory. We do not publish a number we have not confirmed.
Magnesium reacts more readily with the die surface and with oxygen. The film has to be established fast and hold, because the window between clean release and a stuck part is narrower.
Magnesium is more corrosion-sensitive than aluminium, so what the release agent leaves behind matters beyond the next process step — it affects how the part behaves in storage and handling.
Surface condition is harder to hold. A spray that wets differently on magnesium shows up in yield numbers before anyone thinks to blame the release agent.
PROGRAM DATA — Magnesium yield 82% → 95%. A magnesium caster moved from 82% to 95% yield after changing grade and adjusting spray timing. We label this as programme data rather than an independently verified field result, because that is what it is. Where we have a verified figure — such as the die cleaning interval on aluminium housings — we say so separately.
The honest reading of a 13-point yield move is that the grade was only part of it. Spray timing and dilution were adjusted at the same time, and on magnesium the spray pattern does as much work as the chemistry.
If you cast aluminium, use the aluminium range. The magnesium series is built for magnesium and will not give you a fair trial on aluminium. Equally, if your magnesium part goes on to a coating line, tell us at the enquiry stage so we can quote the silicone-free option instead.
We would rather lose one order than sell you the wrong drum.
The questions buyers actually ask before the first drum. Answered without marketing language.
No. Magnesium needs its own base chemistry — it is more reactive, it oxidises faster, and it behaves differently at the die face. Running an aluminium grade on magnesium is one of the more expensive shortcuts in a foundry, because the failure mode is scrap rather than a warning.
ZP-801, the magnesium workhorse, is factory-confirmed at 1:80–100. That is a tighter band than the aluminium workhorse at 1:120–200, and it reflects how much less forgiving magnesium is on film strength.
A magnesium caster moved from 82% to 95% yield after changing grade and adjusting spray timing. That figure is programme data rather than an independently verified field result, and it is labelled as such wherever we publish it.
