TsA4O (ЦА4О) Casting Alloy
Designation
Description
Material overview
TsA4O (ЦА4О) is a regional casting-alloy designation found on drawings for automotive, tractor, electrical and general industrial components. The designation must be paired with the governing standard and required composition because transliteration and legacy documentation can vary. Casting geometry, wall thickness and production route also influence the final result.
Product forms and sourcing
Supply can be reviewed for available alloy feedstock, rough castings, proof-machined parts or finished components. Include the drawing, casting method, rough and finished weight, machining allowance, dimensional tolerances, critical surfaces, production quantity and any tooling or pattern requirement. Availability is confirmed for each enquiry.
Evek LLC reviews each requirement against the requested grade, specification, form, dimensions and quantity. Availability, origin, mill route, minimum quantity and certification are confirmed during quotation; website text is not a stock or compliance guarantee.
Specification and substitution
Do not infer a U.S. substitute from a similar alloy name alone. Composition limits, impurity controls, casting behavior, heat treatment and acceptance criteria can differ. If an alternative alloy is allowed, identify the required mechanical, corrosion and processing characteristics and obtain purchaser or engineering approval before order placement.
The purchaser remains responsible for material selection, design approval and confirmation that the specified material is suitable for the finished component, manufacturing process and service environment.

Standards
Chemical composition
According to GOST 19424-97 in the alloy for the production of pigs the mass fraction of the main components and specific impurities can be changed by agreement of the consumer with the manufacturer.
According to GOST 25140-93, the total mass fraction of lead, cadmium and tin should be ≤ 0.009%. The mass fraction of copper as an alloying element is allowed up to ≤ 0.10%.
