Domite® is a combination of high chromium
white iron metallurgically bonded to a mild
steel backing plate. The white iron has a
nominal hardness of 700 Brinell (63 Rc) providing
maximum abrasion resistance protection for
your equipment. The mild steel is easily weldable
with minimal preparation and acts as a cushion
for the white iron, enabling it to handle impact
and abrasion in the most extreme applications.
This unique product was created for the Australian mining and quarry
industries by Mason & Cox Pty Ltd in 1971 and is now manufactured and
marketed worldwide through authorised distributors for CQMS Razer.
Technical specifications
Domite® has established a reputation as the solution for impact and
high abrasion in the mining and quarry industries, and has numerous
applications in the sugar cane, recycling, cement, mineral processing
and dredging industries among others.

To accommodate a wear surface
requiring more than one Domite® piece,
CQMS RAZER offers back-welding,
a process of welding two or more pieces
of Domite® together on the mild steel
backing plates, to form larger plate sizes
and coverage:

Welding Procedure
Cutting Details
High pressure abrasive water jet cutting is the preferred
cutting method. Thermal cutting using an oxyacetylene
torch, arc-air or plasma is NOT recommended due
to high localized heat input and high risk of cracking
and delamination.
For Domite® no greater than 25mm section thickness,
cutting by abrasive disc is an accepted practice.
CAUTION. Extreme care must be taken when cutting to
minimise local pre-heating or cracks and delamination
may occur.
Cutting Procedure 25mm Section Thickness
1 Secure the Domite® piece to be cut
in a vice or clamp
1 Ensure that the Domite® backing plate and mating
metal surface is clean and flat
2 Welding Rod selection – Low hydrogen weld rods
or gas covered cored wire is recommended
Gas shielded solid MIG wire – Ø 1.2mm max Flux
cored wire – Ø 1.6mm max to ASTM/AWS A5.18
classification ER705-6
Low hydrogen electrode – Ø 3.25mm max to ASTM/AWS
A5.1 classification E7016-1H8 or E7018-1H4
3 Do not pre-heat Domite®
4 Clamp and tack weld Domite® into position
5 Stitch weld, laying 50mm maximum length on each run, alternating ends or sides to minimize heat input
6 Do not deposit weld within 2mm from joint line between Domite® and steel backing plate, as shown in (Fig 1)
2 Notch the backing plate as shown in (Fig 1)
3 Notch the White Iron a minimum of 3mm deep
opposite the notch in the backing plate, as per (Fig 2)
4. Wrap the Domite® with a rag and carefully hit
using a soft faced hammer. The piece should
break cleanly at the notch
Note: The deeper the notch in the White Iron, the cleaner the break.
12
2
CAUTION. Temperature must not exceed 200°C. Excessive heat
input may cause cracking and delamination. Use thermal crayons
to monitor temperature.
Do not weld continuously. Continuous weld may cause warping,
delamination, and cracking.
If a complete peripheral weld is required, use stitch weld
procedure as per step 5.

Forming Procedure
This practice is suitable for Chocky bars only.
Any fitting or
fabrication work
should be carried out
in accordance with
applicable site safety
standards, ensuring
use of approved hard
hats, eye protection,
steel-toed shoes and
protective gloves.
Always use a soft
faced hammer when
performing the work
as descri bed in these
instructions.
NOTE: For severe curves with a radius of less than 305mm, or inside
curves, it is advisable to notch the mild steel backing plate opposite
the ‘V’ to assist forming. (Fig A) The Chocky Bar may crack during
bending. This is normal.
1 Clean the surface to which chocky bar will be welded
2 Tack weld one end of the chocky bar (as per the welding
procedure) in at least 3 places by 15mm minimum length
per weld (Fig 1) Outside Curves: Hammer down unwelded
end of bar with a soft face hammer to bend bar to match
mating radius (Fig 2) Inside curves: Starting in the center
strike bar with a soft face hammer to bend bar to match
mating radius (Fig 3)
3 Stitch weld as per the weld procedure

RUBBADEX®
WEAR
PLATES
A patented acoustic wearplate that
provides all the wear-resistance and
impact benefits of Domite® together
with effective noise suppression layer
of wear resistant rubber or polymer.
Rubbadex® was developed by
CQMS Razer in response to the
growing pressure for quieter
materials-handling environments.
The unique rubber bond in this composite heavy-duty wear plate suppresses noises generated by material impact by up to 13 dbA.
The steel backing plate and rubber sandwich impart toughness to the white iron, and reduce vibration transmitted to the supporting structure.
Rubbadex® is acknowledged for its durability and is backed by CQMS Razer’s commitment to customer service.
Applications
Technical Specifications

A = Results are for plain White Iron casting without a backing plate
B = Results reveal that the impact properties of Domite® is significantly
enhanced with addition of a brazed, mild steel backing plate
C = The addition of a quenched and tempered steel backing plate further
enhances Domite® impact properties by a further 50% and is
comparable to a high strength chrome-moly steel in the fully heat
treated condition

Tunnel Boring Machine (TBM) operating in Gotthard tunnel project in Europe, which is the longest tunnel ever constructed in the world.
There are 4 tunnels in total, each being 59 km long and each having a TBM operating from each end and each TBM were either
completely Lamitized or partly protected with DOMITE®. The project took 10 years and is nearly completed. DOMITE® achieved
a superior wear life over AR 450 BHN hardness steels by a factor of at least 5 times and thus saved the contractors millions of $ in less
downtime and TBM maintenance during the project life.
