The main scope of the article is the development of a computer system, which should give advices at problem of cooper alloys

manufacturing. This problem relates with choosing of an appropriate type of bronze (e.g. the BA 1044 bronze) with possible modification

(e.g. calcium carbide modifications: Ca + C or CaC2) and possible heat treatment operations (quenching, tempering) in order to obtain

desired mechanical properties of manufactured material described by tensile strength - Rm, yield strength - Rp0.2 and elongation - A5. By

construction of the computer system being the goal of presented here work Case-based Reasoning is proposed to be used. Case-based

Reasoning is the methodology within Artificial Intelligence techniques, which enables solving new problems basing on experiences that

are solutions obtained in the past. Case-based Reasoning also enables incremental learning, because every new experience is retained each

time in order to be available for future processes of problem solving. Proposed by the developed system solution can be used by

a technologist as a rough solution for cooper alloys manufacturing problem, which requires further tests in order to confirm it correctness.
