A materials focus.
A global perspective.
JTENK Global Metals & Advanced Materials connects industrial and specialist materials requirements with manufacturing, sourcing and international supply.
A division of JTENK GROUP COMPANY LIMITED, Tanzania, we bring a specification-led approach to metals, alloys, rare earths, oxides and advanced materials.
A dedicated division.
A clear company identity.
JTENK Global Metals is the metals and advanced materials division of JTENK GROUP COMPANY LIMITED. We work with industrial buyers, distributors and research organisations seeking clearly defined material specifications and commercial offers.
Our role spans selected metals manufacturing in Tanzania and the sourcing, trading and distribution of additional materials. The appropriate supply route depends on the product, grade, processing requirements and destination.
Quotations and invoices may use our trading identity while clearly identifying the parent legal entity as the supplier. Product origin and dispatch details are confirmed separately for the offered material.

Metals, oxides and specialist inputs.
From industrial metals
to specialist inputs.
Our catalogue brings together different material families. Grade, form, documentation and availability are assessed for each enquiry.
Gallium & specialty metals
Gallium and specialist metal requirements assessed against purity, form, impurity limits and application needs.
Explore gallium materials →Germanium & high-purity inputs
Germanium, indium and other specialist inputs where purity basis, impurities and physical form matter.
Explore high-purity metals →Rare earth metals & oxides
Yttrium and other rare earth materials, with metal or oxide form, grade and technical documentation specified for the enquiry.

Material-specific origin.
Company location, manufacturing origin and dispatch country describe different parts of a supply chain. We keep those distinctions clear.
Our manufacturing & sourcing approach →Selected metals manufacturing
We manufacture selected metals in Tanzania. Manufacturing claims, processing details and origin must be confirmed for the specific material offered.
A broader materials scope
Other materials are sourced internationally, including certain DRC-origin copper and scrap supplies. Tanzania is not automatically the origin of every catalogue item.
Clarity before commitment
Request the origin, specification and documentation your purchasing process needs. The agreed quotation identifies the applicable material and commercial terms.
A specification-led approach.
Clear information helps both sides make informed procurement decisions.
Start with the application
Define the material, grade, form, dimensions and quantities required for your intended use.
Clarify the specification
Review purity basis, impurity limits, tolerances and documentation needs before confirming suitability.
Confirm the commercial terms
Availability, packaging, origin, price, payment milestones and delivery terms are stated in the offer.
Follow the agreed order
Preparation, required documents and transport arrangements follow the confirmed order terms.
The details behind
a material enquiry.
A purity label is only one part of a specification. We encourage buyers to identify the technical information and acceptance criteria that matter to their application.
Technical documents are requested and confirmed for the relevant grade, batch or order. A general specification is not a substitute for a batch-specific certificate of analysis.
- Purity & impurity limitsState the purity basis and any critical elements or contaminants.
- Physical form & dimensionsSpecify ingots, granules, powder, sheets or other forms, including tolerances.
- Document requirementsIdentify COA, SDS, technical specification, origin and inspection needs.
- Commercial & logistics detailsConfirm quantity, destination, packaging and the agreed delivery term.
Different buying needs.
The same attention to detail.
We welcome both focused material enquiries and broader procurement discussions. The appropriate starting point depends on your organisation, application and qualification process.
Industrial purchasing teams
For production inputs, communicate the specification, acceptable tolerances, incoming inspection criteria and destination. Let us know which requirements are essential and which alternatives may be considered.
Industries & applications →Distributors & recurring buyers
For wholesale or repeat supply, share the proposed order quantities, delivery schedule and documentation expectations. Volume, supply arrangements and commercial terms are assessed for the individual requirement.
Bulk supply & wholesale →Research & technical teams
For qualification work, identify the material grade, required form, critical impurities and documents needed for evaluation. Trial quantities and technical suitability are confirmed in the quotation.
Technical documentation →Understand the material.
